Was too tired yesterday to post it but here is finally the result of the Maevarano formation #paleostream! While not as full of species as other formations the diversity in fascinating, from small herbivores crocs over flying raptors and giant frogs to surprisingly large mammals.
The sediments of the upper part of this formation preserves the remains of a coastal, tidally influenced, semi arid wetland. That is a rare thing to encounter these days, so research into getting a good idea of the environment wasn't easy.
One thing I often do in these cases is put together a mood board with potential inspirations from similar modern day environments. One thing that I picked up was for examples the often times reddish color of coastal wetland plants and the little "plateaus" of plants and soil.
On top of that there appears to be quite a bit of plant material from here but very little is described yet, only thing we have a name on is Sapindipsis which is said to be very common.
I have to thank Discord member JW and @arminreindl for putting together this size chart as well as Discord member LiterallyMiguel for producing a brand new skeletal drawing of Mahajangasuchus!
