Rise Of The Synapsids Is Being Documented Here In Arizona

The track research I've been doing here in Arizona helps document the rise of the synapsids from early amniotes at the end of the Carboniferous to the diverse group they became before their almost complete extinction at the end of the Permian. The two sites I have been surveying and excavating are different environments and different time periods. The newly discovered site is dated to at least 280 million years old, when the area was likely a swampland and river estuary with vegetation like ferns and early conifers.

The site I discovered at the top of the rim in the Coconino Sandstone a few years ago shows a much different environment at 270 million years old. It was mostly dry desert by then and no plant fossils have been found at all, although it may have been close to the shoreline of an inland sea. 

Our abstract for the presentation on the new discovery has been submitted to the Geological Society of America and if approved I will be the presenter at the GSA National Convention here in Phoenix this September.  

People are always asking what the trackmakers looked like, and this excellent video by PBS shows likely candidates from the early lizard-like amniotes to transitional species that led to more advanced and mammal-like animals like Thrinaxodon.

Here is the video I made recently on the new discovery.
