JamieLynn Posted September 21, 2020 Share Posted September 21, 2020 Central Texas has been experiencing a surprisingly cool September plus quite a bit of rain! And that equals some great fossil hunting! I have gone to a few old spots and a few new spots! All in the Cretaceous Glen Rose. I am just constantly amazed at the amount of fauna in the Glen Rose. It seems like I find something new just about every time I go out! I was happy to find a new species of echinoid - a Goniopygus sp. ( very different from the previous Goniopygus I've found) It's tiny tiny, only 5mm. And I found my first really good vertebrate material - a Pycnodont jaw with teeth and a large piece of turtle (plastron?). And even thought it's no echinoid...it's still an echinoderm - my best find of the month so far....a free swimming crinoid! I had never seen one of these but thanks to the Paleontological Society of Austin and our latest field trip, I found this lovely odd little thing! Plus some good Heart Urchins and some nice little Loriolias. Goniopygus sp. 5 mm Free Swimming Crinoid: 1/2 inch (1 cm aprox) Pycnodont Jaw with Teeth 1 inch A small Cidarid Fragment and some Leptosalenia and Cidarid spines A nice Heteraster obliquetus: 1 1/2 inch A decent Pliotoxaster comanchei. 1 1/4 inch A nice little Loriolia rosana 1/2 inch Turtle bone fragment 2 inches 8 www.fossil-quest.com Link to comment Share on other sites More sharing options...
DPS Ammonite Posted September 21, 2020 Share Posted September 21, 2020 Wow that crinoid is neat. If you get it identified it would make a great Collections entry. I can help you with the entry. Jamie, could you please send some of your cool and wet weather to Arizona. This has been the hottest summer ever. Even my forested mountainous collection areas have been too hot to collect in at times. Also, our monsoon season was a disaster. Thanks. 2 My goal is to leave no stone or fossil unturned.

JamieLynn Posted September 21, 2020 Author Share Posted September 21, 2020 oh dear...i knew New Mexico was having problems with Monsoon season (i have a cousin in Silver City) but didn't realize AZ was having issues too! Sending some rainy vibes to y'all!! Of course....the rain today is due to another hurricane in the Gulf... www.fossil-quest.com Link to comment Share on other sites More sharing options...
FossilNerd Posted September 21, 2020 Share Posted September 21, 2020 Awesome finds! I've been enamored with echinoderms since my last trip out and you have some real beauties!

It is aprox 1 cm (1/2 inch). @DPS Ammonite - unfortunately there is no specific ID on the crinoid. I asked Erich Rose (who is president of the Paleontological Society of Austin and all around super knowledgeble guy) and he said that he and a few others have sent their specimens to a guy who is supposed to be writing a paper on them, but it's been a while and it is not published yet. So there is sadly no specific info on this crinoid. 1 www.fossil-quest.com Link to comment Share on other sites More sharing options...

That's huge for a pelagic crinoid. The Cretaceous ones I find in North Carolina are less than 1 millimeter. I've looked through my references for Cretaceous crinoids and couldn't find anything similar to your crinoid, probably something new. 1 Link to comment Share on other sites More sharing options...

erose Posted September 23, 2020 Share Posted September 23, 2020 Great photos. I am still totally PO'd that yall skunked me on the comatulid crinoids. There must have been six of at least two types found, and for me a big goose egg, nada, zippo... The small partial crab carapace was barely consolation. But dang, it was a really nice day after such a seriously hot and dry summer here in Central Texas. PS the first heart urchin is Heteraster obliquatus, not H. texanus*, and the second is Pliotoxaster comanchei. * Smith & Rader (2009) moved the Glen Rose Heteraster into H. obliquatus. If H. texanus occurs in the GR it would probably be much higher in the strata. PSS Smith and Rader (2009) labeled those tiny urchins Goniopygus sp. because they are juveniles and don't yet show the goniopores in the apical plates. They may be in fact one of the other named species in the GR but so far we only find the babies or the adults and always in different places. Cool fossils. Keep 'em coming.

JamieLynn Posted September 23, 2020 Author Share Posted September 23, 2020 Thanks @erose for the ID and info. And I'd ALMOST trade you the crinoid for that crab carapace you found. Almost. I have to say, it is truly due to y'all here on the Fossil Forum and the Austin Paleontological Society that I am the fossil hunter I am....hahhahah!!! Seriously. Thanks to all of y'all. www.fossil-quest.com Link to comment Share on other sites More sharing options...

Pagurus Posted September 26, 2020 Share Posted September 26, 2020 Beautiful echinoids, and that crinoid is wonderful. That tiny little Goniopygus is gorgeous! Enjoy. 1 Start the day with a smile and get it over with. Link to comment Share on other sites More sharing options...
