These may be nothing, but as I have gone around fossil hunting I will often see little clumps like this. The gray one is from Finish Shale in Jack County. The other is from SE Johnson county Texas in a limestone looking formation that may be either Ft Worth or Duck Creek, but I think Ft. Worth is more likely. They often have these little hollows in them as if some animal made a burrow out of them. They seem to be comprised of bits and pieces of shells and tiny pebbles and mud. I think I’ve seen modern crabs make burrows of tiny things with mud mixed in. I find it hard to believe those little burrow structures would survive through the ages, but I’m curious if anyone knows what they are. These have crumbled quite a bit.

I have a gallon jar filled with broken teeth that I have collected over the last few years and tonight I was pulling out some teeth to give away to some freinds kids when I came across these two things that have been in the jar for a few years. The first is a partial Mosasaur tooth which was a welcome surprise and the second a peice of enamel that I am wondering if it could be mammoth or is it wishful thinking On my part. As always, thanks for the feedback.

Ah, yes... that moment when you're out hunting, lying on a shale outcrop on a VERY chilly morning, hunting Pennsylvanian fossils & wishing you had worn a heavier jacket than just a thin cotton hoodie... ... when suddenly you hear "tick... tick tick... tick..." and wonder "What's that noise?" ... then you realize it's from tiny bits of sleet starting to hit the ground around you. It got worse fairly quickly, and I had to deal with a 7/10ths of a mile walk back to the car, across a dam, trying to carry my gear & keep my hood low enough across my face that I could still see, without getting nailed in the face by the rather sharp bits of ice raining down. They were at minimum 1/16th of a inch in diameter, and REALLY stung. Some were even painful through my sleeves! This was NOT in the forecast! (I wasn't alone in this misadventure, but am not naming the other person, unless said person wishes to ID themself.)

I found this nice chunk of mosasaur (?) bone over the weekend at the North Sulphur River in Ladonia, Texas. It has beautiful black enamel on each side that is very smooth and shiny. It has a bowl shaped curve to it on one side. I was thinking it was a rib chunk, but I wasn’t sure with it having the curve. What do you all think? Thank you in advance!

I found this in the water at Post Oak Creek in Sherman Texas. It’s very small, but it seems to have a couple of different things attached to each other. One looks like a rudist??? I don’t know what is attached to the side with the line of circles though. I just thought it was an unusual looking little fossil. Any ideas of what this might be?

I need some help identifying these two specimens. I have collected and cleaned at least 50 of each specimen. The majority of them were found in the upper Glen Rose formation of Edwards, Real and Uvalde County Texas. I've been told that they are both called "deer hearts," even though they look different. Given the different physical characteristics (deep lines on the right specimen and "ears" on the left specimen), I'm guessing that they are different species. My best guess is either Arctica roemeri or Protocardia texana. Thanks!

After a recent post by new member Kyen I decided to post this tooth I found a while back on the Colorado River, TX. I assumed it to be mastodon, but after looking at pics that @Harry Pristis posted, I would like to know if this could be senile gomph chunk?

Found this guy today. It was float material in a creek with eagle ford exposure. Much bigger than anything I've found in this area. Maybe a huge vertebra or pelvic piece? Somebody please say Dino ; )

I’ve never found this in the Eagle Ford. ID please? upper cretaceous 86-90 mya

just got back from vacation in Galveston with the family. Searched high and low for teeth and found nothing so had to hit the creeks closer to home. Hit a high traffic area of Post Oak Creek and did some crawling hoping to find some scraps and found surprisingly quite a bit. Hunted the first day for just a couple of hours and found quite a few P. whipplei, lots of shards and a Native American scraper that was the surprise for the day. On the second day I spent a short hour and a half and found several more P. whipplei a nice complete Cretolamna and two complete S. raphiodon teeth along with the normal shards. I also found a second little scraper just as I was about to leave. That is four scrapers and a point in the last three trips. Not sure why this creek seems to be turning up more artifacts lately but no complaints. We had rain yesterday and the creek has surely flushed up some new things so should be good for someone this week. Thanks for looking. Day 1:

Explored another new North Texas creek. Not many fossils but great for artifacts. We did manage to find one beat up Mosasaur vert, shark teeth and a Gastropod. 10 hour hike. :/

Well this one is stumping my go-to people for blossom sand IDs. Thinking it may be a juvenile but can't place exactly which one it could be. This is from the blossom sand formation in Lamar County Texas, thank you in advance.

I found this ammonite segment a while back in SE Johnson County in an area that is right near the Edwards Formation that is adjoined by a complex area that has Duck Creek and Ft. Worth limestone to name a few mixed in. I tend to think it may have been the complex formation, but I couldn’t tell you what part of it. I found it on top of the ground after a road was put in for a new house being built near some property I own out in the country. It is a segment of an ammonite. It weighs about 10 pounds I’d say. Is about 8 inches long and 6 inches tall or thick. Can anyone tell me about what large ammonites might be in that area?

Found this tooth in N. Texas. 8mm in length. Eagle ford, upper Cretaceous. My guess would be small Archeolamna but unsure. Thanks for any help.

I found this fossil on the Brazos River after hurricane Harvey waters receded. I've found a lot of turtle shell, armadillo and glyptodont scutes over the years. But I've never found anything like this before. It is 2-3/4" L × 3" W × 3/4" thick and weighs 6ozs. Anyone know what this is? Thanks......

Here is a prep I did of a Notopocorystes (=Ferroranina dichrous) nodule (Eagle Ford Group, Late-Cretaceous, Texas) that I got from @Suvi in a fossil trade. This particular specimen had its limitations in terms of missing legs and parts of carapace. I think it is a molt (note what looks like disarticulated ventral exoskeleton on left of top center photo). Luckily, she included several more nodules that may have more complete specimens. This was a good practice one.

Good Morning! My wife and kids are spending a few days on the Texas side of Lake Texoma (Gordonville, Texas). Are there any places nearby that might yield a few of the famous ammonites from this region? Thanks in advance, Daniel

It was a beautiful day at the North Sulphur River in Ladonia, Texas. The river is nearly dry, so visibility was really good for searching. I sifted around the puddles and gravel bars and I found several pieces of baculite, a small gastropod (I love those), and a small piece of tooth enamel (mastodon I believe?) I always love finding that... even if it’s a small piece!

My friend and I found these about 55 miles due West of the far West side of Houston, TX. We are still looking for more at the location so I am being vague about the exact spot. Sorry about that. They weren't very deep in the ground and were found while digging a pond eight feet or so under the surface and the soil is sandy mixed with, clay, and bull rock. This is the only picture I have of what we found and I know it is hard to tell how large these things are but that bone fossil in the right corner is probably 24-30 inches long. I think this is mammoth teeth fossils and mammoth bone fossils but I'm no expert. What do you guys and gals think? Whatever this is its pretty cool to us since neither of us has ever searched for fossils before. We're hooked on it now!

Just thought I'd log my rank beginner fossil hunting expeditions I'm taking with my kids this month! It'll help me be better at note taking, and taking pictures, too. My 5 and 7 year old girls are becoming pretty good little fossil hunters. Sometime in the last few months, it become more of a dedicated hobby rather than an accidental one ("oh look, a fossil!" while on a hike). They've always been interested in them (7 year old wants to be a paleontologist) but hikes specifically to find them have just begun. We are now going out about once a week, sometimes more. The kids spent much of their pre-school years romping around a farm, so sitting inside for 7 hours is not their favorite activity. I try to get them outside for an hour or two each afternoon. Fossil hunting is an easy excuse to hit the great outdoors! I printed out a geological map of our area. I've been working on map reading skills with them from the first day we set foot on a trail, so they are pretty good at it for their age. While I can read all about what fossils can be found in the Eagle Ford group or the Glen Rose formation, not only are my kids just learning to read, but even if they could read well, all the scientific language would be extremely daunting to them. So I'm going for more of an intuitive approach. We pick a trail, note where it is on the map, start a journal entry in our fossil book (trail name, formation, date, weather, etc), and head out. With only a few data points, my kids already have a good idea of where to go and I'm letting them pick the spots starting next week. Our Treasure Map! October 2: Edward's Limestone, 1.5 hours A single find on this trip. Well, lots of algae, tadpoles, POISON IVY and other fun items, but a single fossil find. My 7 yr old spotted it...and LOVES it. Worth the trip. There's a barely visible (in the shot - it's very clear in person) scallop-type imprint on the right face as well. She calls it her Candy Rock because it looks like a Reese's peanut butter cup! October 5: Glen Rose and Bee Cave Marl, 1.5 hours This was a fun learning experience. We started looking right at the junction of two creeks. We searching along one branch for probably 15 minutes without finding anything of significance. We switched to the other branch and were surrounded by fossils. Just 10 feet away from a "dry" location. The kids pointed out the differences between the creeks. They are getting better at spotting good hunting grounds! I think we found most of our specimens in the Bee Cave Marl, but I believe both are exposed very close to each other here. Perhaps not together in this exact location, but certainly along the creek within a close distance. Lots and lots of heavily weathered little stuff. We found a HUGE partial gastropod. I bet it would have been 20 cm long if it hadn't been broken. Didn't get a picture though! Lots of Ceratostrean texanum, Gryphea, gastropods and many "questionable" finds that the kids couldn't resist putting in the bucket. As I sort through them, I'll probably post a few to see if they really are something. Some of them were really neat...but could just be geological. Are we playing in the creek or fossil hunting? Either is fine! The unsorted haul. Willa's favorite find! My favorite find! More to come!
