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! Daniel

Sea-urchin-like spines from Monmouth County NJ (Big Brook)?
njenthusiast posted a topic in Fossil ID
Finally getting round to identifying some finds from over the years at different sections of Big Brook, NJ. I'm going to try and post them in separate topics. The white sea urchin spine is distinctive, but what are these other things? They have similar dots in lines, but the lines are much more spread apart. See that they have pointed ends and one has a wider end. They are about 2-4mm in diameter. Also, any idea or pointers as to what species the Sea Urchin spine could be? I haven't found an easy identification guide on the web yet. -
Just had some recent rain in San Antonio so I decided to go out to a tried and true location. North of San Antonio on 281, there are multiple road cuts where interesting things can be found! Since I joined the forum, I have been amazed at the photos that people take, while the fossils are still in the matrix. I am normally so excited, I forget the documentation. Not this time! I found a few Salenia texana (sea urchins) and a Heteraster texanus (heart urchin). Some before and after pictures have been added.

These guys are so tiny, but are hard like a rock.
