Quick paleoart of a female Tapuiasaurus destroying other females’ nests before laying late in the season, trying to give her own offspring a better chance of survival.
Just a speculative take on sauropod behavior... and an excuse to come back to X

四肢の比率の解析から、アウストロナーガは常時海生の動物で、他の多くの二次的水生適応した爬虫類よりも高度な海生適応を示す。上腕骨より大腿骨が短いことは水生適応の進んだ段階の強力な指標である。アウストロナーガの上腕骨と大腿骨の比率は2.19で、これは全ての海生四足動物の中でも最も高い。

🚨NEW STUDY DROP🚨

New sauropterygian described as Spatulidentatus breviceps. It looks nearly identical to Atopodentatus, but it seems to lack the lateral projections of the snout bones and has different teeth - it was co-eval to Atopodentatus.

A small Brasilodon quadrangularis patiently waits to finally capture a caddisfly called Sanctipaulus, in the Late Triassic of what is now Rio Grande do Sul, Brazil.

Animal of the Day:

Blind Congo River Spiny Eel!

You know how some fish live in caves and eventually lose their sight because it’s dark all the time anyhow?

Well, the BCRSE said, “Who needs a cave?”

The Congo River is like no other river on earth and where we need to start…

Who doesn't like the complete skull of a basal hadrosauroid? Here's Xuwulong, from the Early Cretaceous of China. #ornithischia #iguanodontia

The Precious of Lesotho, a jaw fragment of a giant temnospondyl amphibian that roamed Southern Africa in the late Triassic-Early Jurassic. #fossilfriday
Its name comes from Gollum, from the LOTR, who's author was born in the neighboring country of South Africa, in Bloemfontein.

[🇻🇪Pingu🇻🇪(COMMISSIONS OPENS) @Pinguterra]

Este cráneo le perteneció nada más y nada menos que a Megaladapis, un género extinto de lemures gigantes que vivieron en Madagascar hasta tiempos recientes, de hecho es muy probable que mientras Cristóbal Colón descubrió América, estos increíbles seres seguían caminando vivos

This is laughable. Not least of which because it’s questionable how much a large terror bird would even see an animal as large as an adult Toxodon as prey, let alone something probably over twice as tall as that.

@skeletaldrawing Hope to see more scansoriopterygids soon! Any chance for a Therizinosaurus?
