    The one that got away

    From the album: Chondrichthyan Teeth From The Pennsylvanian Period

    I found this shadow of a tooth that must have popped out of the rock when this rockpile was excavated to make a artificial pond or due to rain. I searched all I could at the base of the rock pile but no such luck. It most likely broke apart as these teeth absorb water and when they dry out it often makes them crack and crumble. I assume this one is a Petalodus sp. tooth as they are the most common i find in the area
  3. 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
  4. Since the weather was beautiful this morning after I did some rowing and grocery shopping, I decided to hit the Oglesby Road cut again. This cut exposes the Pennsylvanian LaSalle Limestone Member of the Bond Formation. This was another great day, I found another Petalodus tooth today, it is nice, but not as nice as the one I found last Sunday. I found a lot of huge brachiopods today after they popped out of the matrix. The exposure- Composita argent
  5. This morning I drove 45 miles to an auction that was taking place in Ottawa, Illinois. This auction takes place every couple of months starting in March and they usually have a lot of Native American objects and usually a few fossils. I the past I have purchased some Coconino trackways and a ton of Moroccan echinoids at a great price. Today I went because I was bored and wanted to see what they had. They had some Mazon Creek fossils in a box, some in a frame, some polished Orthoceras from Morocco, two small mammoth teeth and a 4” meg. The prices that were paid for these fossils was crazy, at l

    Petalodus species?

    Found this past weekend at the Brownwood dam spillway in Texas. White tip was sticking out. Was on a large stone that tumbled from further up. It's really brittle, and was already cracked in the stone. Was trying to take it out with surrounding stone but it came out as I was doing it in a few pieces. Was hoping for a more specific species beyond the Petalodus genus if possible.
  7. Went out for a couple hours last Sunday afternoon. Found a few things that I kept. One tooth I was a couple rains to late. One tooth was just in time because the next rain would have scattered down the hill. And the biggest and best tooth was lucky to see at all in last patch of dirt I was going to look at. Also collected a neat branching bryozoa. And a couple large echinoid plates.

    Multiple Petalodus Teeth Fragments

    From the album: Chondrichthyan Teeth From The Pennsylvanian Period

    A few Petalodus teeth fragments I have found
  9. Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone I have found a few Prehistoric fish teeth in the area such as Orodus, Acrodus, Petalodus and some of their fragments. I believe the right sided one could be a Petalodus but I was not sure since I have not found a black tooth in the area besides this fragment. As for the left, I have no idea but I did note it had beautiful dimples along its surface. While they may be broken I hope that they can provide enough detail for identification!

    Petalodus teeth? ( Missouri )

    Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Hi I was wondering if anyone was able to identify these teeth I found together at the rock pile I hunted at, the right I believe could be a poorly preserved Petalodus tooth with its root and as for the left I have no idea and could be from a Petalodus if not the same one? I am not sure as I am not an expert at identify odd looking teeth yet. If possible I would also like to know the tooth placement if it is able to be determined. Thank you for taking your time to read

    Petalodous Teeth

    To date, I've found 4 teeth, all in the same general area. One is shallow, the others are a big longer. The 3rd is a bit broken, I don't think I have a photo online right now of it. All are attached firmly to the limestone and I don't have any hope of ever getting them out clean. 1st Tooth: 2nd Tooth: 3rd Tooth No photos of this one. Sorry I promised 4 teeth, sadly only photos of three. 4th Tooth:
  12. I've found five Petalodus teeth and have been spending a lot of time reading research papers on them. I got the idea of trying to get released photographs for the 16 holotypes of named species within the Paleobiological database. I got the 16 named species from a list here: http://fossilworks.org/?a=referenceInfo&reference_no=42606 Petalodus ohioensis was easy enough to find, Yale publishes some of their collection online. Unfortunately the one in their collection is only a cast. The original may be lost. This paper has a few, including ohioensis. T
  13. On my way out of town after a family gathering at Starved Rock State Park (it was packed like crazy with people, but I was still able to get a quiet hike in early Sunday morning with my mom. The food at the Lodge is not bad at all, also!) I made time to stop by one of my favorite sites, a roadcut near Oglesby, IL. This steep, talus-covered slope is known to produce generous quantities of brachiopods, as well as rarer shark teeth, cephalopods, echinoderms, trilobites and coral, among other things, primarily from the Pennsylvanian La Salle Limestone Member of the Bond Formation.

    Crinoid and Petalodus Tooth Help

    I am looking for some help on a couple small pieces that I just happened to buy today when I stopped in a small store. I normally would not buy things without proper id’s, but the prices were right. Scale is in inches- The first piece has what I believe are two different Crinoid calyx- the tag stated that it came from Grantsburg, Indiana and it also had “Haney Fm.” Written on the tag. This was on the back of the plate.
  15. We are finally having a little winter weather and the kids and grandkids were here over the last week so the house was getting crowded. We got the kids out for a couple hours to let them run off some energy, at least that was my excuse for a short hunt at a spot near Lake Brownwood here in cen Texas. Kids found a lot of stuff mostly gastropods, crinoids, etc. but my son found a good petalodus. My wife was there so we got a few pictures. It was about 32 degrees with some wind so we only stayed about an hour and a half but I would have stayed longer of course.
  16. Well my family was delayed for a couple days so Christmas day was about 50 degrees and sunny and I was tired of being in the house. I went out to the pit in Coleman County to see what I could see. I don't know if yall have had those days where your fossil radar is broken but I was having one of those days. Had been looking for a couple hours and had not found anything to speak of. Was just about to walk back to the truck but decided to crawl up under some brush that was kind of off the beaten path and got lucky. Its missing some enamel but complete otherwise. Better to be lucky than good.

    Cen Tex, Petalodus

    Went out for a short hunt Sunday after church and found one big broken up Petalodus. I thought I was one rainstorm to late on this one when I saw it because I did not think all the pieces would be there. Got home and was pleasantly surprised that it came out pretty complete. This was found in Brown County, "Penn" near lake Brownwood. Kind of ugly but its big and from a site that I have not found complete ones before.
  18. A surprise find a few days ago in a Brigantian (middle-upper Mississippian) marine shale, Co. Durham, UK. I've been collecting at this locality for years and it's the first tooth I've found there. It's fragile, the left hand side and ridge at the base of the enamel was broken into small blocks and flakes, mixed up with a load of shale fragments. I bagged it all up and spent a happy afternoon gluing it and prepping out the rest. Some knowledgeable friends have helped out with the ID and it's probably Ctenopetalus/Petalodus serratus Owen, depending on which genus is currently in use - I've b
  19. With the rain earlier this week and the sunny, clear, and cool weather yesterday, I decided to take off a day from work and go rock hunting. I decided to head to the Sulphur, IN road cut. A few days before, I reviewed the paper linked from the Falls of the Ohio web page. I had been to Sulphur once before, so I had a small collection of blastoids, some small brachiopods, and some crinoid stems. After rereading the paper, I really wanted to find some of the less common fossils at this site: a shark tooth and a trilobite. Secondary goal was to find a crinoid stem and calyx on a plate. I ar
