Some of the bones from the #Andrés Quarry have been attributed to a dinosaur closely related to 𝘋𝘳𝘺𝘰𝘴𝘢𝘶𝘳𝘶𝘴. The remains consist of some autopodial elements and a dorsal vertebra.
This fossil site provides evidence in favour of a faunal continuity between North America and Europe after the reactivation of the Atlantic rifting formed the proto-Atlantic.
In light of the "Komodo dragons have iron deposited in their teeth" study, I want to know WHY sea lion and fur seal teeth are stained brown/red/black. No other pinnipeds have such teeth, nor do other marine mammals or terrestrial carnivores to my knowledge. Somebody [else] needs to study this!
Know from a dentary fragment only, here is one of the most curious integrants of the #Andrés fauna: a mammal! A more precise identification of this specimen is needed, and time might reveal it to be a Dryolestid, a Therian or maybe something else.
Seems my artwork has been featured in the latest @edgescience.bsky.social video... Give it a watch if you wanna know more about the upcoming WWD reboot!
Among the fossils recovered from the #Andrés Quarry, some pencil-shaped teeth seem to belong to a diplodocoid sauropod. These dinosaurs were very successful at the end of the Jurassic, and multiple diplodocoid taxa are known from Portugal.
Goniopholidids were an ubiquitous group during the Late Jurassic, in Laurasia. These "shield-crocs" have been found in various quarries in Portugal, the most spectacular specimens coming from Guimarota. From #Andrés, remains of "shield-crocs" are known, including osteoderms!
The #Andrés Quarry has produced some of the most spectacular biocenoses from the Late Jurassic of Portugal, right after the Guimarota Quarry in terms of productivity and diversity! The fossils are housed at MUHNAC's paleontological collections.
