parsonsian Posted October 27, 2012 Share Posted October 27, 2012 Here are my crinoids from WY. I've only seen these star shaped ones a few times, once in Terry Dactyll's ammonite (Which is awesome by the way). In the books and articles I've read they're always round. Maybe some day I'll find a better specimen of my own! You can really see the detail in the left photo. Link to comment Share on other sites More sharing options...
Caleb Posted November 2, 2012 Share Posted November 2, 2012 Here is an uncommon Porocrinus fayettensis. What's nice about this specimen is that they are rarely found with stem and arms. Though the arms on this specimen are mostly jumbled, the calyx is fully inflated and the stem is nearly complete.

Wrangellian Posted November 3, 2012 Share Posted November 3, 2012 (edited) Nice ones.. Those star-shaped stems are either Pentacrinids or Isocrinids... we have the Isocrinids here on the Island (upper Cret), but not usually so well preserved or numerous. I have only found bits of the head/arms. Just realized I have not posted this here... it is posted elsewhere but seems like it should be here, even though the same species is already shown and in better shape (trilobiteruss) but my locality is more unusual: Halsam Fm, Mt Tzuhalem, Vancouver Island...

Finally I searched a dry lake bed and there were thousands and thousands of these out there. The best part is that the lake is about 5 minutes from my home. There are also tons of belemnites and gryphaea mixed in too. Link to comment Share on other sites More sharing options...
Wrangellian Posted November 8, 2012 Share Posted November 8, 2012 Sounds like a fun spot to collect! Your stems are much better preserved than mine. Link to comment Share on other sites More sharing options...
