Waco, Texas - Del Rio Clay at the Waco Pit

[hwwii2]

Here are a few interesting items found this weekend at the Waco Pit (Waco, Texas).  What i suspect is an echinoid spine (??) (#1) is something i had not seen before at this location.  I also thought the serpulid (harmulus morton  ??? maybe) (#11) worm tube with its 6 ridges was interesting.

#1 looks like a sea urchin spine to me as well. I can't help you with the ?worm tube. I'm not familiar with the fossils fauna of that formation.

I agree with sea urchin spine. 

The worm genus is Hamulus. (not harmulus). 

Hamulus onyx, maybe?

Hi,

 

Nice presentation. The rule, the numbers on the fossils, bravo. This is not always the case !

Thank you!  The goal was to avoid confusion.  When you see a photo of something like an ammonite, there is no telling what the size actually is.  The ammonites from the Waco Pit are really tiny.  #3 is one of the largest I have found there.  A few miles north (and a few million years in geological history), the ammonites can be two feet across.

This is a very good thing! Most of the time, when people arrive on the forum they put neither rule nor number to their photos, and even sometimes no text. I wanted to give you an example
