I've been out to the Lake Waco Research Area (or just the Waco Pit as many people call it) about nine or ten times so far this year. Over the course of those trips I've found a lot of interesting things such as several species of sharks' teeth, some very small sea urchins, fish vertebrae, and of course the common pyritized miniature ammonites. But I've also found several things that I have yet to definitively identify, such as the three finds that I'm making this post about. First is a small piece of shale with a peculiar pattern that runs off the edge. It reminded me of millipede tracks people have found in Carboniferous deposits and so I decided to keep it and do some research later, not really thinking it was anything special. But to my surprise it seems to match up with pictures of hermit crab trackways (Nereites) quite well, with the indented line representing where the shell was dragged across the ocean floor and the tiny diagonal markings on either side having been made by the legs. I'm not exactly sure why the line in the center of the trackway is depressed into the shale as a negative while the "footprints" are raised positives, however, although it does seem to look that way in some of the pictures of modern hermit crab footprints I saw online as well. The other thing I can't figure out is why the trackway (if that's actually what it is) starts in the middle of the piece of shale rather than continuing off the edge in another direction. If the crab had been dropped onto the ocean floor and then began moving I would expect to find some sort of depression marking where it had landed at the beginning of the trackway but I don't see anything like that. The second find is also crab-related and is one half of a claw. I've found other crab claws before at the pit, but they're usually much smaller and rounded with dimpled marks and come from a species of hermit crab called Pagurus banderensis. This lower half of a claw is larger than a full set of pincers from Pagurus and looks nothing like them. So which Cretaceous crab does it belong to? The last find is a fish tooth. Although fish vertebrae are incredibly common in the pit, their teeth are not. I've only ever found isolated Enchodus fangs before, and this is not one of those. It's much thicker and is proportionally shorter. My best guess is Pachyrhizodus or Protosphyraena but I'm not sure; it could very well be an Enchodus tooth, just a lateral one. Thanks for looking everybody! Any help with ID's is greatly appreciated.

All that was on the label for this item was that it’s from the Permian age and from Texas. I don’t have any further info on it. Does anybody know what this is?

I've been wanting to break down each horse tooth I have and try to identify them...Brandy had me going back to look at my teeth to see if there was anything special about them. Actually , they're all special to me but I never really thought about each one or really any of them possibly being from a different type of horse. So I'll be going over different ones separately because they're all so different starting with this BIG ONE. It's huge compared to the others...so are the other horse teeth juvenile and this a normal tooth? It's just much bigger and I can't figure out why...it definitely has wear on the ends where an ID might be impossible. The other teeth are relatively similar in size but this thing was on some serious steroids. Jk..Or.. am I way off and this is from something else?? The markings that I can see don't seem to compare to anything similar as to the last image of the tooth next to it...which itself is a big tooth but still smaller than this one. Found on a gravel bank in SE Texas. Edit: So I did read they Equus Giganteus did exist in Texas and that there may have been an even larger horse E. Enormis.

Tiniest Shark Tooth You've Ever Seen? POC Microfossil
Mikrogeophagus posted a topic in Micro-paleontology
Just a quick post. Was picking through some washed gravel I got from Post Oak Creek back in the winter when I stumbled upon this guy. I'm surprised my screens were fine enough to catch him. Taking clear pics was a bit difficult so apologies for blurriness. I'm curious about what sort of shark would have a tooth of this size. Was it just a tiny pup or were there just really small species? The hashmarks are millimeters. I might make a post about my POC micro finds once I finish going through it and identifying stuff. It's a long process, but there are plenty of fun finds to be had. Thanks for reading!

I found this today here in SE Texas...the river is down so I thought I'd check the same ole spot...found a bunch of pieces and this cool little one. Actually it's a decent size...hadn't found one of these yet...I just don't know what it is or what it might be from? It's about 4.5 inches total length...could it be bison or something else as big? I took a top, front, back, and bottom picture...then a whole bunch from different views cause I really didn't know how to place it best for an ID. Edit: could it be a cervical vertebra to something?

I've been wanting to check out some of the construction sites in Eagle Ford areas in north Texas, but most of those are well north of Dallas. I'm 60 miles southeast of Dallas, so I'm not often willing to drive that far to scout sites, most of which probably won't have anything anyway. But yesterday, I had a doctor's appointment in Dallas, plus needed to make a shopping stop in north Dallas, so I decided to do a little scouting further north. It was to be just scouting, and I wasn't dressed for any actual fossil hunting. I had on shorts and sandals, and didn't even bring my hat. But, don't you know it, I brought home fossils. One of the construction sites was on a hillside, so the grading done to level it went deeper there, and I stopped to walk a little of it. I found a rock that just looked like a piece of concrete, but I've learned that some of the Eagle Ford fossiferous matrix looks a lot like concrete, so I routinely waste a lot of time picking up concrete pieces. There were no visible fossils in this rock, but when I turned it over, it looked like gray sandstone on the other side. That told me it wasn't concrete, and every time I saw another rock that looked like it, I picked it up. Sure enough, one of the rocks had a small tooth so close to the surface, I was able to pluck it off the rock with my fingernail. Here is that tooth.
