Gnatalie, digital, ~2hrs.
A quarry in south-east Utah has produced a fantastic skeleton, composed of two or more individuals of a diplodocine sauropod. Notably, the bones are green-ish in colour.

Arguably some of the coolest mesozoic crocs were Atoposaurids. At the #Andrés Quarry, various teeth and a partial maxilla seem to belong to a member of this family. The remains are very similar to those found in the Guimarota Mine.

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.

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.

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.

One of the intriguing components of the fauna from the #Andrés Quarry is an enigmatic, and incredibly preserved (including an articulated, anterior half of an individual), sphenodontian reptile!
These fossils, housed at MUHNAC, are yet to be described in detailed!

From the #Andrés Quarry, Portugal, comes one of the most iconic Jurassic dinosaurs: 𝘈𝘭𝘭𝘰𝘴𝘢𝘶𝘳𝘶𝘴! The quarry has produced an extraordinary specimen, a sub-adult 𝘈𝘭𝘭𝘰𝘴𝘢𝘶𝘳𝘶𝘴 with nearly all the skull elements preserved!
