Echinoderms from the Whiskey Bridge, Texas

[dre464]

Hello everyone!

 

I have been picking through microfossils from the Whiskey Bridge locality on the Brazos River in Texas.  I used the hydrogen peroxide technique to separate the fossils from the glauconite matrix, and I have spent hours at the microscope, picking through the material to find the really tiny stuff.

 

Here are a few batches that I've separated...

 

 

 

 

 

 

My reason for posting this in the identification section, however, is that I have been running across a large number of echinoderm fragments and spines...

 

 

 

The largest of the fragments are approximately 8 millimeters across, while the longest of the spines are 6-8 millimeters.  Does anyone have any information on echinoids from this locality?  I'm sure others have run across these before.  Any information is much appreciated!

wasn't even aware of echinoids there, looking forward to seeing what others have to say
