Been working on some paleoart between commission work since I leave for SVP in 2 weeks and dinosaurs are understandably on the brain

Here's a Riparovenator hunting, inkwash and inkpen on a sketchbook that's probably meant for neither lol

[mesozoicmarket]

A partial dinosaur tooth of an indeterminate baryonychine spinosaurid, likely a Ceratosuchops inferodios or Riparovenator milnerae from the Wessex Formation in the Isle of Wight, England. The tooth lacks fluting typically seen in baryonychine teeth, though some positional tooth morphologies that lack fluting have been described from Baryonyx.

ITS TIME

FOR

DINOSAUR MARCH MADNESS 2k23!!!!!!!!!!!!

Starting NEXT WEEK, we begin the ultimate competition:

DMM: RISING STARS

These are ALL dinosaurs that have been discovered in the past five years!!! New friends from old times!!! Including such new fan favorites as Bajadasaurus, Jakapil, Meraxes, and Anachronornis - and that's only four of them!

From the weird to the wonderful, these dinosaurs are here to indicate that just because they were found recently, doesn't mean that they aren't destined to become icons like the names we already know and love. Get ready to learn about some new paleontological excitement - and debate angrily over which ones are better ;)

Round One will go from March 1st through the 7th

Round Two will extend from March 8th through the 14th

Round Three will then go from the 15th to the 21st

Round Four from the 22nd to the 28th

And the FINAL FOUR SHOWDOWN (Ornithischian Vs Sauropodomorph vs Nonavian theropod vs Bird) will occur from March 29th through April 4th!

Thanks to the new tumblr poll feature, reconstructions and mini factfiles for each dinosaur will be on the post with the poll itself! No need to leave tumblr, no personal research, no google quizzes - just rapid learning and immediate voting!

Get ready to vote! Get ready to debate! Get ready... for DINOSAUR MARCH MADNESS!

Round One Matchups under the readmore :)

Spinosaurids!! It’s more than likely this is a post of several different Baryonyxes, Spinosauruses, and 1 (One) Suchomimus. But here’s the intended species

Spinosaurus - Irritator - Suchomimus

Ichthyovenator - Baryonyx - Siamosaurus

Oxalaia - Ceratosuchops - Iberospinus

Not pictured bc it won’t lemme upload 3 more:

Sigilmassasaurus - Riparovenator - Vaillabonaventrix

Protathlitis cinctorrensis Santos-Cubedo et al., 2023 (new genus and species)

(Tail vertebrae of Protathlitis cinctorrensis, from Santos-Cubedo et al., 2023)

Meaning of name: Protathlitis = champion [in Greek, referencing the centenary of the Villarreal football club, which won the UEFA Europa League in 2021]; cinctorrensis = from Cinctorres

Age: Early Cretaceous (Barremian), about 126–127 million years ago

Where found: Arcillas de Morella Formation, Valencian Community, Spain

How much is known: An upper jaw fragment and five tail vertebrae of one individual, as well as an isolated tooth.

Notes: Protathlitis was a spinosaurid, a group of large theropods with specializations for feeding in aquatic habitats. Along with Vallibonavenatrix and Camarillasaurus, which are also from Spain, Iberospinus from Portugal, and Baryonyx, Ceratosuchops, and Riparovenator from England, Protathlitis adds to the growing understanding that spinosaurids were highly diverse in western Europe during the Early Cretaceous.

it is my sworn duty to assign my moots a dinosaur that fits their vibes. this is Riparovenator!

this is absolutely fantastic. i appreciate this very much

Why The Long Faces?

Yesterday, some new spinosaurs out of the Isle of Wight were formally described/revealed. They are very similar to Baryonyx, but as I understand it enough material was discovered to make the argument that Riparovenator and Ceratosuchops are sufficiently different.

To catch the bandwagon of drawing new dinosaurs in a timely manner, here are some shitposts. Enjoy.

Help girl I keep thinking about spinosauridae

[mesozoicmarket]

A dinosaur tooth of an indeterminate baryonychine spinosaurid, likely a Ceratosuchops inferodios or Riparovenator milnerae from the Wessex Formation in the Isle of Wight, England. The spinosaurids from the Wessex Formation were formerly assigned to Baryonyx walkeri which is only described from the Weald Clay Formation.

Round Two: Berthasaura vs Ceratosuchops

Berthasaura leopoldinae

Artwork by @i-draws-dinosaurs, written by @i-draws-dinosaurs

Name meaning: Bertha and Leopoldina’s reptile (in honour of naturalist and women’s rights activist Bertha Maria Júlia Lutz, and first Empress of Brazil and advocate for Brazilian independence Maria Leopoldina)

Time: Uncertain, likely ~121 to 75 million years ago (Aptian to Albian stages of the Early Creataceous) but may be younger

Location: Goio-Erê Formation, Brazil

Theropods are famously carnivorous dinosaurs, but many, many groups of theropods have decided “actually but what if I didn’t” and gone vegetarian, and yet it’s still wild when another one of those pops up every now and then. Even among them though, Berthasaura is special for being the only theropod that seems to have tried to just straight up turn itself into an ornithopod. The long spindly legs, the teeny little arms, and a big head with a toothless beak all come together to create an utterly bizarre little theropod that honestly nobody could have predicted.

Berthasaura is a noasaur, and those of you familiar will at this moment be saying “oh of course it’s a noasaur” because those guys were small ceratosaurs that were basically Theropod Wacky Experimental Phase 1.0. Within this group you’ve got wild sticky-outy teeth, a single weight-bearing toe on each foot in our fellow competitor Vespersaurus, and now multiple instances of beaks evolving independently. Theropods just love to evolve a beak, what can I say? Whatever the hell Berthasaura had going on, it must have been successful because as the basalmost noasaurid currently known its direct lineage has been surviving since at least the Late Jurassic!

Ceratosuchops inferodios

Artwork by @i-draws-dinosaurs, written by @zygodactylus

Name Meaning: Horned Crocodile Faced Hell Heron

Time: ~128 million years ago (Barremian stage of the Early Cretaceous) 

Location: Wessex Formation, Isle of Wight, England 

Say hello to the Hell Heron! Ceratosuchops is one of many new Spinosaurs described recently, showcasing the sheer diversity of this group as well as their much larger spread than previously believed. Ceratosuchops, previously thought to be just Baryonyx, is one of such new taxa that point to the entire group originating in Europe, a piece of their evolutionary puzzle not previously well known. Ceratosuchops was about 8.5 meters long, and had a long crocodile-like skull, with a horn on the top of it (hence its name). As a spinosaur, it would have probably been an aquatic stalker (you know, like a heron) - waiting near bodies of water for food, and snatching it up before it could swim away. Just, the difference between Ceratosuchops and actual herons, well, this was a big heron. It probably wouldn’t have had a sail, though it is possible it may have had a ridge like its close relative Suchomimus. It lived in a heavily river-filled environment, giving it a wide variety of locations to choose from for hunting. Besides a vast diversity of invertebrates, sharks, ray-finned fish, salamanders, lizards, turtles, many kinds of Neosuchians, Plesiosaurs, mammals, and pterosaurs, Ceratosuchops lived alongside other dinosaurs such as Hypsilophodon, Brighstoneus, Iguanodon, Mantellisaurus, Valdosaurus, Polacanthus, Eucamerotus, Oplosaurus, Ornithopsis, Aristosuchus, Calamosaurus, Calamospondylus, Eotyrannus, Neovenator, Ornithodesmus, Yaverlandia, Vectiraptor, Thecocoelurus, and even another spinosaur, Riparovenator!
