🐘 Elephants are part of a group called proboscideans, named for their proboscis, or trunk. Learn more about elephants and their relatives in The Secret Life of Elephants, open on November 13!
Here's some Mammuthus primigenius reconstructions to start your day. Fossil evidence shows that good parents would knit festive scarves to keep their babies warm while their thick fur was growing in.
just a little reminder that it's okay to be tired, friends <3

Strange Symmetries #22: The Whalerus And The Twisted Tusks
Mammalian tusks usually grow in symmetrical pairs with only minor developmental asymmetry, but a few species have evolved much more uneven arrangements.
Odobenocetops peruvianus was a small toothed whale that lived during the Miocene, about 7-3 million years ago, in shallow coastal waters around what is now Peru. Around 3m long (~10'), it was a highly unusual cetacean with binocular vision, a vestigial melon, muscular lips, and a pair of tusks – features convergent with walruses that suggest it had a similar lifestyle suction-feeding on seafloor molluscs and crustaceans.
In males the right tusk was much more elongated than the left, measuring around 50cm long (~1'8") in this species and up to 1.35m (4'5") in the closely related Odobenocetops leptodon. Since these teeth were quite fragile they probably weren't used for any sort of combat, and they may have instead served more of a visual display function.
And despite being closer related to modern narwhals and belugas than to other toothed whales, Odobenocetops' long right-sided asymmetric tusks actually seem to have evolved completely independently from the iconic left-sided asymmetric spiral tusks of narwhals.

The woolly mammoth (Mammuthus primigenius) lived across Eurasia and North America during the last ice age, mostly from the Pleistocene about 400,000 years ago to the early Holocene about 10,000 years ago – altohugh a few relict populations survived until around 4,000 years ago in isolated areas of Alaska, Siberia, and eastern Russia.
Around 3m tall at the shoulder (~10ft), these hairy proboscideans had very long curving tusks that were used for digging out vegetation from under snow and ice, scraping bark from trees, and for fighting.
The tusks showed a lot of variation in their curvature, and were often rather asymmetrical, a condition also seen in the closely related Columbian mammoth. Like modern elephants mammoths may have also favored using one side over the other for certain tasks, which over their lifetimes could result in uneven wear exaggerating the natural asymmetry even more.
Cryptids & Creatures of Folklore Drawtober Day 5 — Woolly Mammoth
Woolly Mammoths were most definitely real animals but they sadly went extinct a few thousand years ago.
However, there have been reports of hairy, elephant-like creatures encountered in Canada within the last few centuries by the Dene, the Inuit, and other First Nations peoples, American and French fur traders, and other hunters and explorers of the region. Some sightings were as recent as the early 1900s.
Did you see this preview of my comic on Iron Circus Comics’ Failure to Launch BackerKit project page and wonder: "what ARE all those animal skeletons?!?"
Well wonder no more: here's a version with every species labeled--scientific and common names both!
