Heterosalenia sp. (undescribed)


Heterosalenia sp. (genus ascertained by JohnJ)

Bottom of Unit 2, Lower Member, Glen Rose Formation, Trinity Group

Albian (Lower Cretaceous) 


These odd little Salenids were first noticed by JohnJ many years ago.  I was lucky enough to find another slightly larger specimen.  This one was hiding in my collection amongst some more common species. These are now being studied and properly described by an actual paleontologist!

You will see the difference in that specimen soon!  As you know, John Jagt has been working on this project for a few years.  Other researchers have also been advised for several years.  Provisionally, this has been named, Heterosalenia rykyrae.
