Fossil Devil by Qilong Fossil Devil by Qilong
This is part one of a piece. Part two is here: [link]

Perhaps one of the most peculiar animals in the question of the study of the origin of pterosaurs, Scleromochlus has been considered a sort of "grandfather" to both pterosaurs and dinosaurs, and as an apparent non-dinosaur archosaur, but also not a crocodylian, it has been notable for framing the debate on exactly what kind of animal it was that pterosaurs could have evolved from.

SO....with dino-fuzz being (likely) an ancestral trait, and with pterosaurs having pychnofibers...Would it be safe to assume this critter had a simple fuzzy covering of proto-proto(?) feathers?
Also the new thought that endothermy is the basal state for archosaurs, with crocs having evolved ectothermy, would this small archosaur be just as endothermal as pterosaurs and small dinosaurs?
Really interesting, this animal.

There's evidence of some type of bony armor on the skeleton, but at the same time, no real evidence for actual preserved filaments. The grains of the rock in which the fossils were found are not fine enough to show evidence of it, and most of these were found as impressions, and not real bones. Despite this, enough people have speculated there were filaments based on the bracketing of pterosaurs and birds that they would not be remiss in adding them. But it is still possible none were present; merely, there can be.

The largest specimens appear to exhibit some vertebral fusion, but ti's almost impossible to tell exactly how old any of the specimens are this is based on, because they are all based on impressions in sandstone, rather than actual bones. No physical body fossils have been found.

Scleromochlus (spelling????) was sent by aliens to confuse us and make my dragon want kids. :omg: :omfg: :laughing: :jawdrop:

Fascinating little creature, actually, and very unusual, if those skeletons do represent adults.

:O_o: That is quite a mystery! I'm not sure if you noticed this, but part two is gone. Anyway, this is quite a find: an animal that isn't crocodylian and is the ancestor of dinosaurs and pterosaurs!
