Paleopedological record (Paleontology 🦕)

The paleopedological record is, essentially, the fossil record of soils. The paleopedological record consists chiefly of paleosols buried by flood sediments, or preserved at geological unconformities, especially plateau escarpments or sides of river valleys. Other fossil soils occur in areas where volcanic activity has covered the ancient soils.

Behind this barbaric name lies a small pterosaur... An adorable physiognomy that I have reconstructed in drawing from existing fossils!

🦖 It is neither a bird nor a dinosaur.
🐦 No feathers or scales, but a rather special coat of hair called pycnofibres
🦇 Membranous wings, supported by the 4th finger, which is particularly long

An article published in the journal "Science" reports the attribution of a fossil mandible discovered in Taiwan to a Denisovan. A team of researchers conducted an analysis of amino acids still present in the mandible and in the enamel of the teeth still present, detecting two variants that were part of proteins specific to the Denisovan species.

Derrière ce nom barbare se cache un petit ptérosaure, dont j'ai reconstitué en dessin le physique et l'adorable physionomie à partir des fossiles existants !
🦖 Ce n'est ni un oiseau, ni un dinosaure.
🐦 Ni plumes ni écailles donc, mais un pelage un peu spécial de poils appelés pycnofibres ! 
🦇 Des ailes membraneuses, notamment soutenues par le 4e doigt, particulièrement long
