Swimming In Petalodus! PSoA Wilson Clay Pit Trip
EPIKLULSXDDDDD posted a topic in Fossil Hunting Trips
Yesterday, I embarked on my second journey with the Austin Paleo Society to a famous spot: The Wilson Clay Pit. It's the site of a former clay quarry that was used for the production of bricks. Though it is in private hands, the land owners are very kind and allow fossil hunters to collect a diverse range of Pennsylvanian fossils on their property. One of prize finds from the pit is the highly-coveted Petalodus tooth. Some of y'all may remember me wishing to find one on my last trip to the Brownwood area, only to realize we weren't at the right sites to find them. Well, if there was a place to- 21 replies

There are few reasons why I would ever wake up at 5 am and begin a two and a half hour drive out to the middle of nowhere. When I saw that the PSoA was heading out to the Brownwood area, I knew it was an opportunity too good to pass up. Everything I had hunted prior might as well have been buried yesterday when compared to the mind-blowing ages of Pennsylvanian and Permian rocks. It's still crazy to think that those formations were roughly three times the age of the oldest stuff I'd seen before. When I peeled out of the parking garage to begin my drive under the stars, I didn't feel an ounce o- 14 replies

I worked out a few crusher teeth this past week. These teeth come from the Deer Creek limestone. They all look pretty similar. Not certain if they are the same, or from different species of fish. The second is the smallest ive found. I know form genera is an issue with these too. Anyone have any insight? #1 #2 #3

Deltodus Shark Tooth? PSoA Pennsylvanian Trip to Brownwood
EPIKLULSXDDDDD posted a topic in Fossil ID
So 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. O -
The next Burlington teeth found this summer to have been termed Deltodus. My ability to differentiate Deltodus from Sandalodus, Helodus (small), and Psammodus is nonexistent. So even though labels say Deltodus, the true identity of some may be the other three genuses. I am open to any suggestions that veer away from a Deltodus ID. Like Chomatodus, Deltodus is a Chondrichthyan. There seems to be 2 general physical types. Blacker teeth seem to be larger and have smaller pores. Lighter colored teeth seem to be smaller and have larger pores. Is this a way to differentiate types??

I was working through some Burlington Limestone, Mississippian looking for the Chondrichthyan fossils found within. Most primitive shark teeth in this matrix are fairly small, which is why this unknown surprised me when discovered. My suspicion is Deltodus except for the massive size. I welcome all thoughts on this ID. Unfortunately the missing pieces were not found. @Elasmohunter, this one's for you!!!!!!!!!!

Over the past year, I've become fascinated with the often bizarre fish and sharks of the Pennsylvanian. Fortunately, my home state of Illinois is a great place to hunt for such fossils. I've shared several of these in other posts before, but wanted to put everything together in one thread. Probably won't have much to post for a few months after this, but once summer rolls around, I should hopefully have plenty of new finds to share. I would say there are three major settings in which you can find fish fossils in Illinois: Mazon Creek, black shales, and limestone. I have not had luc

I know very little about shark teeth. I found this one a while back in Pennsylvanian (Desmoinesian) shale in northeastern Oklahoma. I am speculating this may be deltodus only because I see a nearly identical tooth labeled as deltodus on another website. The fossil is very thin (too thin to photograph the edges). Besides confirming the taxonomy, can anyone tell me which surface of the tooth is shown in Side A? Finally, would you say Side B is mainly matrix (other than the edges)? I think matrix is showing through the cracks on Side A, and that may be the only thing holding the fossil together.

From the album: Pennsylvanian Fossils of Northeast Oklahoma
This is one of the crushing teeth of Deltodus, from Pennsylvanian (Desmoinesian) shale in northeastern Oklahoma. This tooth is only about 4 mm thick. Deltodus comprised a genus of cartilaginous fishes in the class Chondrichthyes, subclass Holocephali. Modern day holocephalans include chimaeras.-
