Skull of a dinosaur with a hollow tube on its head found for the first time in a century

The duck-billed dinosaur Parasaurolophus is best known for the tube that grows out of its head; this well-preserved skull offers more clues about the crest’s evolution.

New research published today in PeerJ  on an amazing specimen of Parasaurolophus from the Fruitland Formation of northwestern New Mexico. The amazing preservation of the skull reveals in detail the bones that make up the iconic tubes, demonstrating that the crest of Parasaurolophus is constructed just like those of other, less tubular, lambeosaurines. The new skull also helped to firmly establish the validity of this species, P. cyrtocristatus, and links it with other “southern” species!.The fossil was discovered in the BLM managed Bisti/De-Na-Zin Wilderness, underscoring the importance of public lands for science. The region is also part of the ancestral lands of many indigenous groups including the Dine (Navajo Nation) and other Puebloan people, making this an important heritage fossil as well.

Here we have 3 angles to look at this #Ichthyosaur jaw and associated #bones. 🦴
This “sea dragon” lived in the ocean during the #Jurassic era, back when #dinosaurs roamed the land. The #fossil was found at Ravenscar on the Yorkshire coast of Britain. 🇬🇧

While Doryaspis nathorsti here looked a bit like a weird prehistoric sawfish, it was actually an ancient jawless fish more closely related to modern lampreys and hagfish.

Measuring just 15cm long (6"), this odd little fish lived in the shallow seas of what is now the Arctic Svalbard archipelago, around 407 million years ago during the early Devonian period when the region was located in much more tropical latitudes.

It was part of a group called the heterostracans, a lineage of jawless fish with heavy armor covering the fronts of their bodies. They had no paired fins and relied solely on their powerful tails for propulsion, and some like Doryaspis also developed large stiff wing-like projections from the sides of their armor that acted like hydrofoils to provide extra lift while swimming.

But the strangest feature of Doryaspis is that pointy serrated saw-like “snout” – which wasn’t actually a snout at all, but instead formed from a part of its jawless mouth roughly equivalent to the lower lip and chin.

It’s unclear what the purpose of this appendage was, but it might have been used for prey detection, probing around the muddy seafloor in a similar manner to sawfish or the big-chinned porpoise Semirostrum.

I don’t know why picking pigeon as representative of bird line-archosaurs is extremely hilarious to me.

“They can’t yet speculate as to whether the gigantic bones belong to a known species or something new entirely, but, per CNN, the team says that the specimen could be even bigger than a 122-foot, nearly 70-ton titanosaur called Patagontitan.. Researchers have dated the new specimen to around 98 million years ago, reports Harry Baker for Live Science.”

Cosmosaurs update!

Thank you everyone so much for all the enthusiasm on my last post! I hoped you would enjoy them but I was surprised by how much positive feedback they recieved!! Y’all’re awesome.

I’ve put together a few mockups of how I plan to colour these! The space background I think will be in watercolour, and the swirly clouds I will attempt to make in gold leaf! Haven’t used it before so we’ll see how it goes!

Therizinosaurus lived in the Late Cretaceous of Mongolia some 70 million years ago. This dinosaur could grow to more than 33 feet longs and weigh more than 6600 pounds.

The recently described Erythrovenator jacuiensis from Late Triassic Brazil. This is one of the oldest known theropods. This reconstruction is highly speculative since this animal is only known from a piece of thigh bone.
