you never realize just how tiny platypus are until you see them in person!

(male study skin and articulated skeleton at the Cleveland Museum of Natural History)

the museum's closed off for a full reno right now, but there was an event this past Monday I went to with all the different departments having tables to show off what they do. ended up having a really nice time and talks with the staff! also learned they're 3d scanning their primate skull collection and putting them online, they had this super old gorilla that was massive they were showing the equipment off on. :o

History Giants: Titanichthys clarki

Ti. clarki is among the largest known placoderms we have fossil record off, remains of their jaws, skull and shield bones are found scattered but some complete specimens offer a complete view of this peculiar and possible first large filter feeding vertebrate from the late devonian. AMNH 7315 or AMNH FF 7134 (IDK why the different ID from Engelman reference) represent one of the biggest known specimens recovered alongside the Moroccan Ti. termieri, having a head length of 75 cm and extended flat a breadth of 1.4 meters.

Engelman paper on Dunkleosteus body calculation used the measurements of this specimen alongside the smaller but quite complete CMNH 5768 implementing OOL giving on both specimens a body size of 3.7 and 4.15 meters respectively, making this one of the few placoderms that can rivalice in length to Dunkleosteus.

Reconstructing Titanichthys

If you are wondering about some details on this reconstruction looking this way, proportions, shape of the head and the strange "fang" on the front that lacks many recons is because I spend some time trying to check how to reconstruct properly this armored fish, which ended up with this skeletal reconstruction

This already comes from what I tried to do several months ago with the need to properly reconstruct this placoderm since the available figures and references seem not to expose several elements, even those that we do know exist which are not often highlighted in the paper skeletal reconstructions. in this case the base of everything is mostly from CMNH 50319, perhaps one of the most complete Titanichthys with material described online (scale bar 1 m)

I was not just comfy about doing this reconstruction based only in sketches, so instead on assuming proportions by digital sketches in a 2D way, I spend few weeks working my way into blender and modeling each pieces I did build a basic model from most of the bone that forms the whole skull and thoracic shield bones, the model for the moment is not available anywhere, and I don't think I could share it online for the moment.

Every minor thing that is not know is being filled with other of its relatives such as Bungartius and Tafilalichthys, both species the most close relatives on few cladistic trees. Unlike the filter feeder, these two are known to might have been hard prey eaters, they are relatively more complete and better preserved so they work out as a reference base being one of the most useful aspects the lacking elements of the jaw.

Probably is important to remark a lot of mounts that are used as references are pretty incomplete in the front, with also the lower jaw being backwards, the extreme of the jaws should be touching in V shape and the notch probably was filled with cartilage called a meckel's cartilage.

In general picking Bungartius as a sample the upper jaw possess the complete set of superognathal plates, the upper jaw bones that exist on all placoderms, in many species vary in size and shape, which even Titanichthys there is some evidence of a Posterior Supergnathal Plate along the complete specimen (PSG, see above), but not the Anterior (MG or ASG), inferring from the position of both supergnathal and the articulation of the cheek bone where the inferognathal fits, this hypothetically could mark how these bones configurated in the skull.

Eye with this, my reconstruction is speculative, based on how these bones articulates on other specimens, new evidence and more material could provide a more accurate conclusion.

Compared to Dunkleosteus is amazing that level of diversity these reached on the last days of the Devonian, both belonging to two totally different radiations of Arthrodira they grew to become the giants of their time, though currently with this body reconstruction Dunk remains very robust on body shape compared to the more compact shaped Titan.

BTW for those curious how it would look like with its jaw closed.

i'm the person who posited "all dinosaurs are birds" after your one poll. since then i went to my local museum (cmnh) with my partner and another friend, and suggested my theory to one of the educators in the hall of dinosaurs. he said "you're wrong by scientific consensus, but i respect that this is the insane hill you're choosing to die on." i also mentioned your blog and he said he's a fan!

Excellent :D

and yeah, the whole "all dinosaurs are birds" thing is something that will produce groans at every paleo conference

A More Complete History of America

Section 1 - When to Begin?

Folsom, Clovis and The First Debate

Part 2 - Clovis

There is some dispute on the true type site of the predecessor of Folsom. The Type Site, the first site to be formally described to a scientific audience, often dictates naming rights. This leads to some academic saltiness and state rivalry. In the interest of fairness, we’ll actually start in Colorado.

Along the South Platte River, southwest of the small town of Milliken, Colorado once stood the Dent Railroad Depot. In 1932, strong Spring rains exposed several very large bones in a sandstone gully west of the tracks.

The son of the Depot’s manager informed his geology professor, Jesuit priest Conrad Bilgery. He took some of his students to the site in September of that year, where Father Bilgery determined the bones were that of a mammoth and contacted Jesse D. Figgins.

Yes. The same Figgins that was the Director of the Colorado Museum of Natural History.

Figgens sent a museum staff member to excavate the remains, though Father Bilgery and his students were allowed to assist. In the end, 13 partial skeletons from 5 adult females and 8 young mammoths were sent to Denver, along with two intact stone points.

Figgins published the find in the Proceedings of the CMNH in 1933 - the museum bulletin essentially - describing the points as belonging to a Late Ice Age culture.

Sadly, internal museum publications don’t count. I don’t make the rules.

In 1929, EB Howard was part of Alden Mason’s Southwestern Expeditions as a representative of the University Museum of Philadelphia. They had come to the Guadalupe Mountains west of Carlsbad, NM to search for archaeological sites, and were quickly directed by local Bill Burnet to a cave locally known for its artifacts.

It's unclear how long the predominantly white local population had known about the cave. Burnet reported it had once been sealed, but he and his brother had busted through the stacked stone wall. At some point, they had dug 3 or 4 holes,each about a yard deep. Beads, pieces of sandals, hide, and several baskets, one containing charred bones (which may have been human remains as cremation was practiced in the region at various times in the past) were all removed.

Still, the site was relatively intact. The pits had been dug straight down, and, aside from stones and debris being moved at the surface, most of the ground appeared undisturbed.

Excavations began in 1930. As Howard and the team had hoped, by the time their trench hit that 3 ft deep mark, they were in undisturbed soils. Like most caves and rock shelters, Burnet had little stratigraphy, or distinct soil layers, to go off of and they were about 30 years from widespread radiometric dating, so they attempted to date the cave using the common method of the day: identifying Cultural Horizons.

This meant, quite simply, looking at whatever turned up in their trench and trying to identify the age of that layer by the artifacts it contained. More baskets, sandals and bags found in those between about 1.5 and 3ft down indicated a Basketmaker Culture (an uncreatively named Pueblo precursor). They found several burials, which were likely the reason the cave had been sealed.

Above the Basketmaker layers were no distinctive artifacts beyond what had been scattered near the surface by looting. Again, the fact that the cave had been closed off to all but pack rats and other rodents had stopped later people from using it.

It was about 2 feet below the burials, however, that EB Howard made a more unexpected discovery. Among the bones of bison and musk-ox, some of them charred, were thick lenses of ash and charcoal. Hearths. Along one of these rested a fluted stone point that Howard described as Folsom-like. Several bone awls for sewing hides or making beads were also recovered.

Howard was very careful in his initial report of the site in 1931. He made a point of describing the interior of the cave, its geology, condition, and included multiple sketches of the layout. He reiterated that the cave had been sealed, hiding it for generations. He discussed how pack rats could have gotten in and built nests and middens at the surface, but that there was no evidence of burrowing or middens near the remains or below them. It was doubtful, Howard expressed, that the stone point or awls could have been deposited so deep by rodents.

EB Howard took that point to the 1931 Pecos Conference. Among the people he showed it to was Frank Roberts of the Smithsonian.

Cannon AFB was once a small local airstrip. By the early 1930s, it had been named the Clovis Air Field and was expanding. Some of the gravel for the new road construction came from nearby Black Water Draw, a seasonally dry valley crossed by small channels from the infrequent rains located along the Llano Estacado Plateau. The Dustbowl had already stripped away some of the surface layers, and while quarrying workmen revealed, you guessed it, large animal bones. They also turned up a large tooth and a stone point.

In 1932, as he was finishing work at Burnet Cave, it came to the attention of EB Howard that points like those at Folsom had been found in the area. He and his team swung by Clovis to look around, guided by locals AW Anderson and George Roberts, who themselves had taken a keen interest in the site.

The first point had been found by a workman with the gravel company, along with a mammoth tooth, when they had first reached the blue-gray layer at the gravel pit. This was the point that George Roberts had notified Howard about. Roberts had secured the point from the workman and shown it to Howard when he arrived in Clovis.

“The workman, whose honesty I do not question, showed me the spot where he had ploughed up the tooth and this artifact, and there is no doubt in my own mind that they both came from the blue sand on the west side of the gravel pit.” EB Howard

The point itself had been broken long ago, before the workman had uncovered it, as evidenced by the lime crust and was similar to the points from Folsom and about 4 inches long and 2 ¼ in wide, and “extraordinarily thin - ⅛ in at its maximum thickness”.

The summer field season was almost over, but Howard had the opportunity to explore Black Water Draw and view some of the artifacts and bones that had been found. That fall, machinery uncovered another mass of bones in a layer of blue-gray sands below the gravel layers.

Like at Burnet Cave, Howard made detailed notes of the site and its surroundings. Black Water Draw as a whole was dotted by the remains of ancient lakes, ponds and channels. On its western edge and near the Texas border, there were still a few alkali spring ponds. Likely, the Draw had once been a tributary of the nearby Brazos River, or at least drained into it. Where the gravel pits had been dug revealed a clear view of the geologic layers or strata to well below the bone bearing layers.

The bone layers, blue-gray sandy clay, were near, but not at the top. These were water deposited and held many species of diatoms, tiny water dwelling animals, which still live in fresh and saline waters. These diatoms, and the bones of the mammoths and bison, allowed Howard and his team to determine that the blue-gray sands had been deposited in the late Pleistocene, near the end of the Ice Age.

Howard could not begin a full excavation until the summer field season of 1933 and spent the next 4 years in Clovis. On the east side of the gravel pit a flint scraper and charcoal, presumably from a campfire, were among the bones of extinct bison, the first in situ objects found. More scrapers and knives were uncovered near the pit. In a section of Blackwater Draw Howard named the Anderson Lakes, a thick lense-shaped layer of charcoal contained the charred bones of bison (found all over the Lakes), small mammals and birds and a selection of blades and shapers. None of the Anderson Lakes artifacts appeared to be of the “Folsom-type”, even though they came from the same deposits of blue-gray sands.

No mention of a new “Clovis-type” appears in Howard's 1935 report. Instead it included a great deal of discussion of the geology, such as the diatom studies, and theories of how such a site could have come to be. It's here that Howard relays a story from Prentiss Gray, who had studied bison and in 1887 had observed a herd of some 4000 attempt to cross the South Platte River when it was low. “Soon the leaders were stuck in the mud, those behind, pressed forward by the herd, trampled over their struggling companions until the whole bed of the river a half mile wide was filled with dead and dying buffalo. This habit of stampeding was a habit of the wild buffalo.” Howard also shared similar accounts of antelopes in the Congo and Guanacos in Patagonia who had trampled each other or become trapped in frozen mud.

Howard also devoted part of his report to explaining honestly that he, his team and even the other prominent scientists they had brought to Clovis or otherwise consulted, can't say for certain that there had been no mixing of artifacts and layers at the site. Firstly, at and near the windblown surface, were scattered Yuma style points. These were known to be old - no contemporary peoples were known to use points quite like them, but they were from long after the Ice Age. Other points, some Yuma, some of other styles but all of that same old but still recent manufacture, and some pot sherds had been recovered from layers above and within the blue-gray sands. While never found directly alongside the older, unidentified and Folsom-like tools, these finds cast a shadow of doubt as to the antiquity of the flints.

It was in 1937 that JL Cotter, Howard's primary partner on the excavation, published the final report on the The Occurrence of Flints and Extinct Animals in Pluvial Deposits near Clovis, NM (part IV). Though he did not formally classify the points as a new type, this is where they start being referred to as a distinct style that had only been reported before from the Dent Site and Burnet Cave.

By the 1950s, the fluted points had become called Clovis Points and their style and method of manufacture was known to be a precursor to Folsom technology. Radiometric dating, though it would need future calibration and refinement, would first be done in the 1950-60s, returning dates of nearly 10,000 years before present, well within the known range of the late Ice Age.

Hrdlicka died in 1943, and would never accept the findings at Folsom, Clovis or anywhere else.

"Pursuant to the policy, the Carnegie also recently removed from its Hall of Egypt the skull and bones of an individual that had long been displayed to illustrate archaeology and ancient burial practices."

i guess i can understand not using a real human skull for the diorama they are removing bc it was literally just a person being attacked, but isnt showing ancient egypt burial practices the literal purpose of a museum like cmnh. looking at thousand year old bones does nobody harm. these people in academia think so fucking hard about everything when the average person going to a museum just wants to see mummies and cool old shit. i'm so sick of this

Mọi khi tôi nói nhiều về hạn chế trong nhận thức và tư duy của phụ nữ rồi. Hôm nay tôi sẽ nói về những điểm ấu trĩ & ngu dốt trong nhận thức của bọn ĐÀN ÔNG.

Đầu tiên, trong giai đoạn hẹn hò (tìm hiểu nhau), tôi thường xuyên thấy các bạn đặt nghi vấn bị gái "lợi dụng" hoặc "đào mỏ".

Quan điểm của tôi là ntn:

Thứ nhất, những thứ mà các bạn nghĩ là mình đang bị "lợi dụng" hoặc "đào mỏ" là gì? Trời ơi, đa phần là dăm ba bữa ăn uống quán bình dân, dăm ba buổi xem phim, dăm ba tiền phòng khách sạn nhà nghỉ... Chấm cmnh.

Nào có nhiều nhặn to tát gì cho cam?

Ví dụ, mới quen mà gái đòi bạn buổi hẹn đầu đi ăn tôm hùm, buổi hẹn thứ hai gạ mua iPhone thì tôi đồng ý có dấu hiệu đào mỏ. Nhưng kể cả khi như thế, bạn vẫn có quyền từ chối cơ mà?

Tóm lại, tất cả những khoản liên quan "tình phí" phải chấp nhận là phí tổn của game tình ái, không nên nghĩ đó là gái lợi dụng hay đào mỏ mình.

Thứ hai, gái thật sự muốn đào mỏ, thì họ cũng phải chọn đối tượng phù hợp, là những thằng GIÀU THẬT SỰ. Đó là logic cơ bản: Người ta chỉ mất công "đào" cái "mỏ" có đầy tài nguyên khoáng sản, chứ không ai rảnh đào cái mỏ rỗng cả

Đa phần các bạn đều làm công ăn lương với thu nhập trên trung bình, cá biệt có bạn là single dad, đã ly dị và mỗi tháng còn phải gửi tiền chu cấp nuôi con.

Vậy nên tự hỏi mình CÓ GÌ để người khác muốn "đào" trước khi nghĩ họ đang "đào mỏ" mình?

Trừ khi các bạn thật sự dồi dào và sung túc về mặt tài nguyên và nguồn lực vật chất một cách không cần giấu diếm (nói ngắn gọn là GIÀU thật sự), còn lại tôi khuyên các bạn không nên có suy nghĩ đó.

Tiếp tục, những cái NGU KINH ĐIỂN khác của đàn ông trong giai đoạn hẹn hò tìm hiểu gái còn có, thôi dài quá rồi để hôm khác tiếp tục.

Vài dòng.
