Tylosaurus specimens have been found with stomach contents including the remains of turtles, sharks, sea birds, plesiosaurs, and even other mosasaurs. For the Lizard King, everything in the Cretaceous seas was a potential meal.

Alternate version with a bit more soft tissue on the neck. It's not clear if they had a seamless transition from head to body, like ichthyosaurs and cetaceans, or necks more like regular lizards.

Over 60% of the length of the plesiosaur Albertonectes is made up of its neck, which is the longest relative to body size of any animal ever discovered. At 76, it has more vertebrae in the neck alone than most species have in their entire bodies.

The traditional concept of "Alamosaurus" is now believed to represent multiple different species of large North American titanosaur. Some of these have been suggested to be relatives of South American lognkosaurs like Patagotitan and Puertasaurus, though this is far from certain.

While its anatomy is not as thoroughly studied as that of T.rex, well-preserved skeletons in multiple stages of growth allow us to reconstruct the life history of Tarbosaurus much more clearly than its North American cousin's... especially after Zanno & Napoli (2025).

Starting off 2026 with a remake of one of my oldest works, Patagotitan! Even though it's not the largest, the completeness of its remains makes it one of the most impressive dinosaur discoveries. Seeing a cast of the skeleton in person was absolutely breathtaking.

Merry Christmas!
While the genus Acrocanthosaurus is currently only known from a single species, differences in the skull of the largest known specimen suggest that the giant sail-backed carcharodontosaurs may have been more diverse in North America than we thought.

Update: I forgot to fill part of the lacrimal with white, it's not so freakishly thin at the bottom.

Shuvosaurus is one of the most incredible cases of convergent evolution in fossil reptiles - it was mistaken for an ornithomimid dinosaur for more than a decade, but as a pseudosuchian, it's more closely related to crocodylians than to any dinosaur.

Aside from its eponymous short crest, Parasaurolophus cyrtocristatus differs from the other species in the genus by having proportionally longer limbs. It was once suggested to be the female counterpart of P.walkeri, but the two lived at different times.

As well as being the largest and geologically youngest species of Parasaurolophus, P.tubicen also had a crest with a rougher surface texture than its closest relatives (perhaps suggesting it was covered in keratin, unlike the fleshy or scaly crests of most other hadrosaurs).

The iconic head crest of Parasaurolophus had a series of internal channels that could have created trombone- or tuba-like sounds as the animal blew air into them, making it one of the very few dinosaurs for which we can actually try to reconstruct the original sounds.

I literally made this one months ago and forgot to post it here.💀
Like many living animals, the horns and frill of Triceratops are highly variable between individuals, so much so that nearly twenty species have been attributed to the genus (only two are still valid today).

Triceratops horridus, the species depicted here, is the smaller of the two - the later T.prorsus could reach about 9 meters in length, and likely rivaled or exceeded the largest T.rex in weight.

After spending days/weeks working on a skeletal of your own, you can easily recognise when the creative liberties, unpublished material, or specific quirks you incorporated into your artwork have been used elsewhere. It’s frustrating because there’s not much you can do about it.

The monstruous alligatoroid Deinosuchus is famous for fossil evidence of having preyed on hadrosaurs and tyrannosauroids, although it seems to have preferred sea turtles. Compared to modern crocodilians, it had a massive skull, even relative to the enormous rest of the skeleton.

And now for something entirely different: the (approximate) sizes of every dragon in the A Song of Ice and Fire universe. Thanks to @Fang83768513 for help with wingspan estimates and the Meleys silhouette! (1/2)

(2/2) Final five, because Twitter wouldn't let me post them all at once. Silhouettes marked with '?' are dragons we haven't yet seen in the TV shows.

The largest named megaraptorid (though not by much), Maip shows a more typical state of preservation for the group. Its presence confirms that megaraptorans held the apex predator niches in part of South America right up until the end of the Cretaceous.
