Echinoid Jackpot! 7 species! 3 need help ID'ing - Texas Cretaceous

[JamieLynn]

I found "A SPOT" finally!! Found 7 species of echinoids, and am over the moon! I am able to ID some but not all. Could use a little help please! Location: Comal County near Canyon Lake TX. Cretaceous Glen Rose.  I'll post pics of the others i have tentatively ID'd in the comments post,  I would appreciate confirmation on those too. Here are the ones I am not sure about: I thought these first ones were Coenholectypus, but they are very "off center". But they could just be squished. 

Is this Pseudodiadema perhaps?

Perhaps too small and busted up a specimen to ID. 

Thanks for your help!!

These I think I have ID's correctly. For sure the first one is Pygopyrina hancockensis! Yay!! Second one I think is Orthopsis comalensis and the last (and most exciting for me even though it's TINY pieces) Is Paracidaris texanus

 Nice finds.

 

What formation are these from? Also, give us a general location such as county, town, creek etc.

Crikey, sorry. In my excitement I forgot to put that. Comal County near Canyon Lake TX. Cretaceous Glen Rose.

See this wonderful paper on the 22 species of Glen Rose echinoids.

Congratulations! Nice finds. It's sweet to have your own honey hole isn't it? Yay!

yes indeed!! I'd been "stabbing" in the dark for a while trying out different places, stratas, colors of rock.....I have a very general idea of what to look for, but I am not trained in geology or paleontology so I'm kind of teaching myself! Learning as much as I can with the help of the Fossil Forum!!

Well done.

Jolly nice finds and congratulations on your new spot.

Must be a nice spot! Can’t help with the ID’s, but the specimens are lovely.

[JamieLynn]

thanks y'all! I think I have narrowed them down thanks to some help from FB fossil friends. Pretty sure the first three are indeed Coenholectypus. I was thrown off because the top "points" seem to be off center, but they might just be crushed that way.  The next two are probably Pseudodiadema.

I think you can call your spot "precious"...lol; And echinoids are one of my favorites, the patterning in them is always astounding. 

[JamieLynn]

hahhah! Well, I was kind of crawling around on all fours.....so yeah....appropriate!

The more you try, the better you get. The better you get, the harder you try. It's a vicious circle, but heck, somebody has to do it.

hahhaha!! True that!
