EPIKLULSXDDDDD posted a topic in Fossil IDBack at it again with some more specimens I hope to pin down an ID for. These are also from the Adams Branch Limestone/Winchell Fm of the Canyon Group. My method of slowly scouring through every stone around me paid off when I found these beauties. Finding a nice crinoid crown was a big goal of mine coming into the trip that I was pretty sure I wouldn't fulfill. It feels good to come away with so much more than I expected! We'll call them crowns 1, 2, and 3 from left to right in the images below: Crown 1 was super exciting for me when I initially came across it, but Melvin's enthusiasm amped me up even more. Although it's compressed, the "bulb" (idk the correct terms) is fairly complete with all of the plates and even some little spines protruding off of it. There are the beginnings of arms springing out as well as the first segment of the circular stem coming out the bottom. The plates for this guy are very bumpy. I've come to the tentative ID of Ethelocrinus magister, but I do not have much familiarity with crinoids so please, please correct me if I am mistaken. Once I pin an ID, I plan on making my debut in the find of the month contest! Crown 3 is only the very bottom, but has a similar bumpiness so I think it's the same species. Here are some more angles of crown 1: Crown 2's preservation is worse and I am unable to tell the original texture of the plates. I think it's smooth, from what I can see, so I've arrived to the ID of Delocrinus inflexus, though I realize a solid ID may be impossible. It's not very complete, but it shows some arms and some of the crown so I think it's still pretty neat. Here are some additional pics: The underside doesn't show much: To help inform y'all more, here is a pic of the two types of crinoid plates I found that day. Many bumpy ones and the occasional smooth kind: Thanks for reading
EPIKLULSXDDDDD posted a topic in Fossil IDSo today I went on my first trip with the Paleontological Society of Austin to the Brownwood area to visit a couple of Paleozoic sites. It was a blast and just what I needed after a busy week. However, I'm not gonna go too far into the details because I plan on writing up a trip report soon. I think I found some pretty cool stuff . Instead, I'm writing this topic because I am simply too anxious to wait on hearing an answer to this question I have. Our first stop was along a roadcut that was situated within the Pennsylvanian Adams Branch Limestone (Canyon Group) and Strawn Group. Our trip organizer, Melvin, told me that Petalodus teeth had never been found at this site (I didn't get to ask if Deltodus had been found because I couldn't remember the specific name at the time). I was a little bummed out to learn of this, but that did not totally erase my hope of catching a Paleozoic shark tooth. Anyways, I got to thoroughly looking through the roadcut and eventually came across this tiny specimen that I have yet to clean: I didn't think much of it at first, but I quickly noticed that it had a pattern of white speckles all over its black surface. The specks were so small, I couldn't 100% confirm whether they were pitted, though it felt like there were pits when I gently ran my nail across the surface. I was soon reminded of the Deltodus teeth I had seen in my prior research, though I of course forgot the name . It was quite small and had some strange angular shape to it that somewhat resembled the crinoid crown plates that are common throughout the site. I showed it to some people far more knowledgeable than I in the Pennsylvanian, but couldn't seem to get an answer. After taking it home and looking at some images online, I'm still confused, however I am beginning to slowly favor Deltodus tooth as an ID. My hope is that someone can either confirm this or snap me out of my pareidolia. It's hard to get nice pics using my phone, but I have tried my best. Here are some closeups followed by a Deltodus tooth I saw for sale online from Kansas City that looked similar. Here is the tooth I saw online. I want to note the pattern of the speckles. They are hard to describe, but the way in which they are positioned in wavy lines seem, to me, to match across the specimens. Additionally, I believe the general shape of my fossil, although smaller, appears to be similar to what's pictured below. I am not sure if my "tooth" is complete or fractured. Eagerly waiting to hear what y'all think
