Tetrapods of Niobrara Formation by Kana-hebi Tetrapods of Niobrara Formation by Kana-hebi

Tetrapods (Sauropsids) of the Niobrara formation, a geologic formation in the United States of America deposited 87-82 million years ago during the Late Cretaceous. It was once the Western Interior Seaway, an inland sea that divided North America into 2 continents (Laurasia on the West and Appalachia on the East) during much of the Cretaceous. Includes a varied fauna of pterosaurs, dinosaurs, turtles, plesiosaurs and mosasaurs.

Fabulous work! But what about Thalassomedon? Is that not a Niobrara taxon?

No. Thalassomedon is not part of the Niobrara chalk

Anyways, I know Elasmosaurus wasn't part of the Niobrara Formation.

You know what else wasn't?

Oh, yeah; didn't notice that.

However, I was referring to Archelon.

¡Impresionante! Me encantan los colores de los hesperornítidos. No sabía que hubiese tal diversidad de tortugas marinas en la formación. Todos hemos oído hablar de Archelon o Protostega, pero hay mucho más:D (Big Grin)

Mosasaurs, Mosasaurs everywhere!!! Amazing work recreating the fauna of the Niobrara ecosystem but two questions: 1. Was not Elasmosaurus also present in this formation? 2. Was not Pteranodon sternbergi renamed Geosternbergia?? Out of this, great composition friend. I expect more like this one!!!

Thank you very much! Elasmosaurus platyurus is only know from Pierre Shale formation. Reports from Elasmosaurus from Niobrara correspond to taxa in the synonymy of Styxosaurus, or to remains too fragmentary to classify beyond the family ranking. Geosternbergia in my view, and that of many people, might not be sufficiently different to represent a different genus. furthermore Dawndraco (another genus of pteranodontida) is, in my view, nothing else but a syonym of P. sternbergi.

they should have countershading, like other large, marine tetrapods. look at sharks, sea turtles, cetaceans, penguins, etc

counter shading works when the bottom is white and the top is black. not striped

:iconmegabass22:
megabass22 Featured By Owner Mar 14, 2017  Hobbyist Traditional Artist
No. It means that the coloration on the upper side of the body is darker than the coloration on the underside. It does not have to be black and white.
