Impression of Thyreosaurus atlasicus, a recently-discovered stegosaur from the mid Jurassic of Morocco that is unusual among its kind for having rows of plates that lay flat against its body, rather than standing vertically as in other genera such as Dacentrurus, Stegosaurus and Tuojiangosaurus.

Keiko Yamamoto walks down a trail that leads into dense forest with a juvenile and an adult Torosaurus latus.

A Gorgosaurus libratus feasts upon a recently killed Spiclypeus shipporum 76 million years ago in what is now the Judith River Formation of Montana; Three small Azhdarchids and two Enantiornithids arrive to take scraps that the large predator has left behind.

Cover for the first episode of my webcomic series “Dinosaur Planet Remade” which focuses on a lone female velociraptor’s quest to start a new family of her own after she had lost her previous mate and chicks to a rival male.

BREAKING NEWS!!! Of all the dinosaur discoveries of 2024, this is the most astounding of them all…for a new species of gigantic titanosaur has just been described today from the Candeleros Formation of Argentina! Sumotitan gigas, at 40 meters long and 80 tonnes in weight, is by far the single largest and heaviest sauropod ever to have lived in South America, and it shared its habitat with the equally gigantic apex predator Giganotosaurus carolini and fellow sauropods Andesaurus and Limaysaurus.

Here’s the link to the PLOS One paper “An Enormous New Titanosaur from the Candeleros Formation of Argentina” if you’re curious to find out more about the description of this spectacular dinosaurian colossus:

Skeletals of two Dacentrurid stegosaurs that both hail from the El Mers lll Formation of Morocco 168-160 million years ago and were both described within four years of each other, from bottom to top: Adratiklit boulahfa and Thyreosaurus atlasicus.

Three Amigos: Allosaurus Edition

Impressions of the three different species of the Late Jurassic carnosaurian theropod dinosaur genus Allosaurus, which lived in Laurasia 155-145 million years ago, from top to bottom: A.fragilis and A.jimmadseni, which both hail from the Morrison Formation of western North America, and A.europaeus, which hails exclusively from the Lourinhã Formation of Portugal.

As an 8.5 to 9.7 meter (28-32 foot) long fleet-footed predator that was capable of making rapid vertical movements with its neck and had a very wide gape which enabled it to bite repeatedly into the flesh of its quarry, strong jaw muscles in spite of its weak bite force, and grasping hands that were armed with large talons, Allosaurus was superbly adapted to prey upon the ornithopods, sauropods, and thyreophorans that were abundant in a semiarid environment that had distinct wet and dry seasons and flat floodplains that were home to river-lining forests of conifers, ginkgoes, horsetails and tree-ferns as well as sprawling fern prairies, and it also shared its habitat with other large, powerful theropod predators such as Ceratosaurus, Marshosaurus and Torvosaurus.

Celebrating 200 years of Megalosaurus bucklandii, a 6-meter-long theropod which lived 166 million years ago in the Middle Jurassic what is now southern England, and on February 20, 1824, was also the first genus of non-avian dinosaur ever to have been given a valid name.
