Lake Jacksboro TX Microfauna


JamieLynn

Recommended Posts

Took a little trip to Lake Jacksboro spillway and concentrated on the microzone hoping to find some of the little goniatites and nautiloids. Only found a couple that were "big enough" to see , but once I went through my bag of matrix, I was happy to have found quite a few of the microfauna! A few I am not sure of the ID so any help is appreciated! All of these are 1/8 to 1/16 inch

 

Goniatite Peritrochia sp.

A few other nice little finds

 

I think this is a shark spine:

A scaphopod Plagioglypta sp.
