Re: [dinosaur] Parasuminia, new anomodont from Upper Permian of Russia



The site seems conflicted over whether _Suminia_ was arboreal or aquatic!

Note that _Suminia_ was not the only tree-living vertebrate known from the Late Permian.  There were also the gliding weigeltisaurids (like _Coelurosauravus_), known from around the world, and certainly arboreal (and likely scansorial as well).  (Scansorial/arboreal abilities were once proposed for the Late Permian dicynodont _Cistecephalus_, but subsequently refuted [Nasterlack et al. 2012 DOI: 10.1080/02724634.2012.697410].)

Note that the Vyatka Paleontological Museum has even named its website suminia.com. See this page (in English) about anomodonts with photos of specimens of Suminia and a reconstruction.

Incidentally, the Late Permian anomodont _Suminia_ has a big claim to fame: It's been interpreted as arboreal, and therefore the earliest known arboreal vertebrate (Fröbisch and Reisz, 2009 doi:10.1098/rspb.2009.0911).  As well as its very long limbs, _Suminia_ has been described as having an opposable thumb, and possibly even a prehensile tail.

A recent paper not yet mentioned:

A. A. Kurkin (2017)
A new Galeopid (Anomodontia, Galeopidae) from the Permian of Eastern Europe.
Paleontological Journal 51(3): 308–312
DOI: 10.1134/S0031030117030042


A new anomodont genus and species, Parasuminia ivakhnenkoi sp. nov. (Galeopidae), from the Sundyr-1 locality (Upper Severodvinian Substage, Upper Permian) is described. Based on morphological analysis of tooth wear, the type of work of the jaw apparatus similar to that of Suminia Ivachnenko, 1994 is revealed.
