  1. Fossilized Snails?

    This is my very first post on The Fossil Forum. I was hoping for some experts to weigh in on what exactly are these fossils. I picked them from a lake shore in Central Texas. Can you please tell me the species? What are the approximate ages for these? Why did they go extinct? Thank you for all of your help. Dubs
  2. Central Texas fossil hunt

    I took a advantage of the cool weather today (low 90's) and headed out to Central Texas near Waco. This was first time hunting in the Texas Paw Paw formation ( The Paw Paw Formation is a geological formation in Texas whose strata date back to the late Albian stage of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation). I didn't find any dinosaurs , but found plenty of ammos on the cliff and in the creek bed. It was an interesting experience finding few ammonites. Here are few photos that I snapped today. Beautiful day lower 90's. Creek water level is always low this time of the year. I found this complete ammo sticking out of the cliff. Typical Paw Paw formation. Got my trusty old tools out and hammering out the ammo. Other Ammos are in the creek bed, but badly worn. Got one out!
  3. Please share some wisdom

    Hello everyone. I am new to the site so please let me slide if this is incomplete. I found this fossil in a small Creek in the west part of Dallas county in Texas. This area is upper Cretaceous but this bone is in amazing condition in my opinion so maybe more recent?? It is currently in storage so these are the only pictures I have right now. Any info or suggestions would be awesome and appreciated
  4. Central Texas Flint rock

    From the album Central Texas Flint Rock

    Found these rocks over the weekend. Excellent spark material.
  5. Found this in Comanche Peak limestone formation in Central Texas. I'm thinking Eoradiolites quadratus but not sure if there's enough info to nail down species. Apex to apex measures approximately 1.5 cm for three different samples. I will slowly post more pics of the other specimens, as I reduce photo sizes without losing quality. Thanks for your help.
  6. My daughter and I are looking for new fossil-finding adventures in central and Northeast Texas. We have already been numerous times to Ladonia, Sherman and Mineral Wells. We also like to hunt for arrowheads!
  7. Hey folks, If you are here in Central Texas today, the Texas Memorial Museum is having their annual Identification Day. 1-5 PM at the museum on the University of Texas campus, here in Austin. https://tmm.utexas.edu/events/3 I will be there along with some other members of the Paleontological Society of Austin to assist in identifying your fossils. We will be handling the invertebrates but there will be others helping with vertebrates, both fossil and extant, rocks and minerals, as well as artifacts and other natural items you might be curious about. TMM's Identification Day is part of the Austin Museum Partnership's annual Austin Museum Day, a FREE community-wide exploration of museums in and around Austin.
  8. A Cross-section of Something, Perhaps?

    This peculiar thing caught my eye while I was out looking for urchins, clams, gastropods and all of the other bountiful fossil blessings of Central Texas. This was in an intermittent creek cut in the Comanche Peak formation, Lower Cretaceous period, western Bell County, Texas. The scale in the background is inches (sorry, no metric device readily available). The oval shape of the fossil is 1.5 cm by 1 cm. All of the lines you see making up the fossil are crystalized sediment within the limestone matrix. My 8 year old was excited about how "sparkly" it looked under the flashlight. In a couple of the pictures you can see what appears to be a very small section of the side of the fossil. I am stumped on this one. My hunch is that i'm seeing the inside of an organism that we typically get to see the outside of. But i don't know what the insides of the urchins look like. Seems too oval to be a cross section of phymosoma texanum. Maybe it was a plant or coral? Could it be a flattened-out, crystalized Parasmilia?
  9. In the continuing saga of finding all the echinoids of Texas.....I found a few new things plus re-assessing my collection I found I already had another example (albeit small bits only) of another! So here are my latest finds (and re-finds). In my collection from Marathon Tx was a couple of bits of (I think) an Archeocidarid!! Stopped by a little creek in Austin and found this lovely Coenholectypus: Went on a little road trip to Glen Rose TX and found what I thought was a Loriolia but on closer inspection, it's a Goniopygus! Not a great specimen, but slightly better than my previous ones, so still looking for a nice one: And the piece de resistance : A Balanocidarid Spine!! Practically in my own backyard (well, within 30 minutes drive anyways)
  10. Hello all!! Was in Bell County and found this little bit - Fredericksburg Group Cretaceous. It seems to have an interesting structure. Apparently some "fishy bits' have been found in the area...is that what I have? Thanks!
  11. Fossil Fest

    Hey all you local Central Texas folk. It's time for Fossil Fest. This is the annual show of the Paleontological Society of Austin. Next weekend, November 3 & 4, Round Rock, Texas. Family friendly, lots of stuff to see including displays by our members, including me, hourly door prizes, grand door prizes and a nice variety of dealers. Follow this link for details: https://austinpaleo.org/fest.html Hope to see you there. Erich Rose President, PSA
  12. I own some property in Blanco County, Texas and there are many fossils and fossil imprints embedded in the rock along the creek that runs through the property. I would love to know what these fossils are. I am posting just 2 pics because of size restrictions. I know nothing about fossils but am fascinated by the ones I have found. Any help would be appreciated.
  13. We found this working outside of Horseshoe Bay Texas. Can anybody identify it? thanks
  14. Central Texas Fossil ID

    Not a particularly exciting ID request, but these have been driving me crazy. I pick up tiny fragments of these in the North Sulphur River and Post Oak Creek, and picked up some bigger chunks while hunting in central Texas lately. On the "exterior" the striations run vertical, but on the cross sections the striations are horizontal. On larger chunks there are sometimes a layer of pocketed material on the back. Is it petrified wood, shell fragments, some type of enamel? I keep grabbing these things without knowing for sure what they are, and I'm ready to toss them if I can't figure it out. http://imgur.com/a/qwKtl Any help is appreciated. Thanks y'all!
  15. Hill Country Fossil Club

    Hi ya'll! Just a little reminder that we have a small group of avid (amateur) collectors who get together for meetings and hunts. We usually meet in New Braunfels and do our hunts fairly locally (San Antonio, Austin, Canyon Lake, San Marcos). We'd love for you to join us! Much of our ommunication is done via the facebook Group: https://www.facebook.com/groups/1467355426848631/or feel free to email me at jamielynn@gmx.com. Come fossil hunting with us!!
  16. Hill Country Fossil Club - Texas

    Hello there, my name is Cameron and i'm starting this topic to have an open page for the flow of ideas and information about the possible formation of a Hill Country Fossil Club for San Antonio, Austin, and the surrounding areas . This idea has been proposed before on the forums, but it didn't work out, so i'm doing my best to pull everyone together to form some sort of club. It could be anything from an organized monthly meetup for group fossil hunting trips, guest speakers, etc. to a simple email list for members to invite a couple tag-alongs on their upcoming trips. However it takes shape, it'd be beneficial to alot of the central Texas members of the forum to form a local fossil community. So far, my idea is to maintain the facebook page created last time (for those who prefer facebook) and make an email and phone number list so each club member gets a reminder when someone plans an open-invite fossil hunting trip, or if there is a meeting coming up, or anything else of that nature. If interested in making a list, pm me your email and texting phone number with whatever name you like to be called. If alot of people prefer to meet first, thats fine too. Maybe we can make a field trip out of it. Just reply with your thoughts and let's all start exchanging ideas. If it doesnt work long-term again at least we have a few new locals to hunt with, lol.
  17. I got in a nice sunset hunt last night. Heavy rain has washed a little of my hilltop spot away and I found some good stuff... A beautiful scallorn point, some 19th century glass, some shells, and a few unidentified things that caught my eye. They all either just looked out of place or appeared to have some form. Some might just be weathered rock. These were all found in Burnet County, Texas on the Eastern Edwards Plateau. I found a snapped stalactite base in this same formation so there might have been a cavern at some point at this spot. Thanks for looking.
  18. Central Texas Cretaceous Id Help

    Hi all! I had an excellent hunting trip up in Round Rock Texas with a friend yesterday. Lots of exogeria, small heart urchins, oyster shells and such. I did find one thing that I can't identify. It reminds me of a squished barnacle. The striations are on both sides. Any ideas?
  19. I was visiting the local museum of a small town near San Antonio and found what I think is a mammoth tooth amid their collection. The curator just thought it was an unusual rock that had been donated before he came to the museum. In the exhibit, it was on the floor next to a crumbling tombstone. I took a few pictures with my phone, but did not think to include a scale. From memory, I'd say it is around 6-8" long, 4-5" wide, and about 3" deep. What do you think? Did I get it right?
  20. Tracking The Glen Rose

    January 2, 2010 The Lower Cretaceous Glen Rose Formation (Kgr) of Central Texas is roughly 110 million years old. Its classic exposures look like man-made steps or solid blocks that are occasionally interrupted with softer rock or marl. The formation is typically divided into upper and lower units by a layer of Corbula fossil clams. Just below this layer was the destination I wanted to find for my first fossil hunt of the year. It takes its name from the isolated occurrence of an ornate fossil sea urchin - the Salenia texana zone! A bright dawn had not yet thawed the frost when I headed to meet my friend, Bob. He was excited to show me a new quarry where he had found echinoids the previous month. When we arrived at the site, he oriented me to the most productive layers in the formation, and we started hunting the youngest strata. I immediately began to find fossils. Erosion of the shelf, we were searching, left fragments of 'heart' urchins, gastropods, and bivalves everywhere. I was trying to be selective, looking for the better preserved specimens, but it was hard to pass up an unusual oyster or clam. Oyster (Ceratostreon weatherfordensis ?) with the partial mold of the shell where it was attached Juvenile Arctica sp. clam Soon, Bob was calling out, "Spiny urchin!" with periodic repetition. He wryly commented, "I just seem to be a magnet for those things." Meanwhile, I gouged my elbow on rock as I crawled along the ground. Glancing to check the damage, I spied one of the small, prickly echinoids. It was just one of those small moments...that capture your love of the outdoors. The late morning light was perfect, and when I reached for the camera, a little heart urchin caught my attention. Even better. So, I digitally captured the two 'echies' before putting them in my box. We finished the morning and the rest of the layer with several more echinoids and a partial crab claw. Loriolia texana echinoid with Orbitolina texana foram Heteraster obliquatus echinoid among Orbitolina texana forams Loriolia texana echinoid Some finds after a little cleaning From this area, we moved down into the "zone". A hard limestone bench capped a six foot thick layer of softer rock. It weathered into chunky clay before a transition back to solid stone. Even within this bracketed strata, I noted some subtle differences in the coloration and hardness. But meanwhile, Bob had started finding echinoids while I was "getting the lay of the land". The marble-sized Leptosalenia texana were eroding with regularity from the top half of the zone. A small, disk-like foram, known as Orbitolina texana, littered the ground. Scattered among them were a variety of different gastropods and a non-fossil caterpillar. Leptosalenia texana with forams and gastropods Caterpillar Leptosalenia texana echinoids Bob previously mentioned that he had found a couple of plates (a part of an urchin's shell) from a very uncommon echinoid on his last visit. So, as we leaned against the wall of the formation, I asked him what else he remembered. He described them as being more whitish in their preservation than some of the other finds we were making; and when he said it, I thought of the variation in the rock I had seen earlier. We had already found fragments of the spines which the 'Salenia' urchins used to protect their shells; but I was not tracking them - we were tracking a cidarid echinoid! In the Glen Rose Formation, two species have been described: Phyllacanthus texanus and P. tysoni. So, I grinned when I saw part of a larger, bumpy spine sticking out of the rock. About that time, Bob suggested that we move over a short distance to a fresh spot. Hunting anything, with success, requires identifying and following certain clues. In the new spot, I put my suspicions to the test. A few feet below the caprock, I found a lighter layer that was somewhat hidden by runoff from layers above. I flaked away the debris to get a better look and immediately started to find several spine fragments! I announced my excitement, "Cidarid spines!" Echinoid spines 5 cm echinoid spine in matrix A slightly elevated heart rate accompanied the anticipation of following signs in the rock. Then, I had an adrenalin spike when Bob called out, "You need to look at this." He walked toward me, and in his hand were 3 connected plates of our cidarid urchin quarry. I showed him some of the spines and explained the "hidden" layer we could focus on. I thought we were close to our treasure, and he asked if I had "covered" the area just to my right. I told him, "No, go ahead" as I knelt down for a look at some of the spines eroding from the ground. "JOHN!" I turned to see him stand up beside me with a golf ball-sized, knobby echinoid in his palm! "You did it!" I yelled. "You really...did it! Way to go!" We stood a moment, looking at the rare urchin with a range of emotions. Then, he handed me his prize while he went back to get his camera. I put it back in the spot he picked it from and took a few photos. When he came back, more photos ensued...it was an amazing Texas find! Although I know quite a few cidarid urchins have been found through the years, I am personally aware of just five...including Bob's - certainly not a common discovery. Checking a few references later indicated he had found a Phyllacanthus texanus! Bob's discovery Phyllacanthus texanus echinoid Well, as you can imagine, the adrenaline of discovery had us quickly back in search mode. More spines were found. I ravenously scanned the layer we isolated. Then, my "heart jumped in my throat" when I spotted the partial test (shell) of another Phyllacanthus! So close...but not this time. My Phyllacanthus texanus partial test Late into the fading light, we searched to no avail. The cool wind and darkness ended our efforts, and we congratulated each other with our goodbyes. Hopefully, with some weathering and heavy rain, we will get another chance to track the rare fossil urchins of the Glen Rose.
