I got this a year or so ago, but this was bought as, possibly an ankylosaurian from the Woodbine Formation at Dallas Fort Worth Airport, Texas, USA. It is in pretty rough shape, so I don't expect the best results, but I'm hoping it is an indet. narrowed down to at least Ankylosauria. It looked like it could be a Nodosaurid indet. based on shape. A high chance of it being a complete bust, but I didn't spend much on it so it I figured it was worth the risk for a rare locale. Forgot to take a picture with a measurement, but it's roughly 4.5mm tall.

These past few days, I've been running around North Texas to a handful of sites, some old some new. The reason for occasion was the arrival of a couple of our own forum members to the DFW metroplex, my current stomping grounds. I was excited to show off a few of my favorite sites and have the opportunity to explore something new in a short span of time. One of my first forum friends ( @Jackito ) had some work to do in Dallas along with a couple afternoons to kill for fossil hunting. I decided to take him to a couple of spots that had fossils unlike anything found down in Austin. Our first stop was at my new Woodbine outcrop one sunny evening. The pocket did not disappoint this time around and Carter found himself a nice Cretodus, Cretoxyrhina, and several croc teeth! I didn't have the most luck, but I've got a baggie of the rubble that is promising for micros or so I hope. We finished the final hour of sunlight at my ole Pawpaw site. I was hoping we could score a bunch of crab carapaces, but we got a bit skunked in that department. Plenty of complete Engonoceras ammonites and crab claws were had at least. I sent Carter off to a Kamp Ranch site for the following day. I haven't seen his finds from there just yet, but I heard it was a good hunt. Another forum member friend, @LSCHNELLE coincidentally visited DFW this weekend. Anyone familiar with him knows that he is the craziest ptychodus fanatic on the forum. He and I had been planning a Paraptychodus expedition for awhile and Saturday was set to be the day. Before that though, we made a visit to my Atco site in hopes of scoring some Early Coniacian Ptychodus. Sadly, we got completely skunked and almost had serious trouble when a giant tree limb fell just feet away from us. A Long Story Short Lee had some secret intel on a possible site where we could find the elusive Paraptychodus washitaensis, the oldest species of Ptychodontiformes. When we met up, I told him I had a good feeling about our chances to which he agreed. We spent the morning walking around the place looking for any indication that we were in the right area, but nothing seemed to match. After finding a whole lot of nothing three hours in, I could sense that we were both beginning to feel defeated. Instead of calling it quits there, however, we decided to change our focus and take a long shot at another spot. As we walked along the new outcrop, I searched the exposure while Lee poked through the talus. Things were going smoothly as we began to find the usual Duck Creek stuff including a pretty little shark tooth. The atmosphere was very serene, but that took a quick turn when I heard Lee excitedly shout, "PARAPTYCHODUS!". I almost couldn't believe it at first, but then I saw the unmistakable transverse ridges of the oldest Ptychodontiformes known to science. We were filled with a renewed energy and got straight back to hunting. Pretty soon I came across my own smaller Paraptychodus specimen and an extra half of a tooth on top. After a handful of smaller shark tooth discoveries we were nearing the end of Lee's visit as he had a long way to go back to Austin. We turned around and started making our way back the route we came. The majority of the fossils had been in the talus, but I took an ambitious path looking at the exposure. I focused on a darker spot of interest in the wall that I had initially written off as just another oyster. As I looked closer, I saw its wrinkled surface and hollered for Lee to come over. In my hands was a pristine and quite large Paraptychodus tooth! It was more than anything I could've hoped for! My best Paraptychodus washitaensis (mesial tooth) My first Paraptychodus washitaensis. Note the preserved root Posterior Paraptychodus washitaensis A vert I think is sea turtle? A strange fish jaw. Any ideas?

Well to say I'm surprised by today's hunt would be a monumental understatement. I've hunted the Woodbine for about a year now, and the most I had previously found were some leaves and beat up bivalves, despite visiting many sites. Not this time though... The recent string of good fossil luck I've been having prompted me to humble myself. I decided it was time I made a return to the dreaded Woodbine, a formation I have a complicated relationship with. While it's a very beautiful formation with a diverse range of unique animals and plants, Texas hunters will likely relate when I say that it is one of the most difficult to find reliable success on. Despite wasting countless hours wandering creeks, construction sites, and lake fronts in the past, I still have a fondness for the time I spent trying to pick it apart. I thought this hunt would be the same, taking in spectacular sandstone scenery, but very little in fossil department. As soon as I stepped out of my car, the Texas heat wave hit my face full blast. It was about 99F with hardly a cloud in the sky. As I walked to the exposure I had marked, I was quick to take notice of the lack of shade. I spent a solid hour wandering around, not finding much besides bivalve fragments scattered sparsely at the foot of the hill. Already, I had downed a water bottle and felt my eyes stinging from sweat. At the far end of the exposure, I began climbing the hill and came across a thin, pebbly layer of purple matrix. It was unusual in that I hadn't seen matrix like it in the Woodbine before. It only encapsulated a small area. It was absent from the section only 10 feet in either direction. My recent experience with conglomerates in the Atco and Hawaii prompted me to investigate further. Within seconds I spotted a bluish white crown to a flat tooth, Pseudohypolophus mcnultyi (Brachyrhizodus mcnultyi favored by some). There wasn't a doubt in my mind that I had finally found the spot I was looking for. Pseudohypolophus mcnultyi, the most common tooth of the day. I had stupidly forgotten my rock hammer and chisels, so I was left to begin breaking apart the conglomerate with my hands. Doing so exposed new teeth at an absurd rate. I was taken aback when I laid eyes on an Onchopristis dunklei rostral... and then three more. These are much rarer in other formations, but they seem to be COMMON in the Woodbine! Onchopristis dunklei. They are shattered, so they will remain in matrix. I managed to find two fragments of a mid-sized Cretodus semiplicatus tooth that fit perfectly together. Also snagged a couple of Cretalamna catoxodon and Haimirichia amonensis, staples of the Cenomanian shark fauna. Cretodus semiplicatus. One of the most beautiful shark species in my opinion. Cretalamna catoxodon with some turtle bone below. Haimirichia amonensis. The fun continued with a chunk of shark cartilage. Wish there was a way to pin a species to these... Shark cartilage There were also invertebrates to be had. Most of the time they were bivalve steinkerns, but now and then some crustacean chunks would show up. Bivalve Linuparus sp. segments. Something crustacean. Kinda shaped like mudshrimps found in the Pawpaw Fm. Later into the day, I came across a strange ridged tooth I suspect is reptilian. It is quite thin and sadly most of it isn't there. I'm hopeful it's something cool like pliosaur. Prepping it out of the this tough matrix is a real challenge. Unknown ridged tooth. Of course I had to save the hands down best find for last... a small reptile tooth! I believe it belongs to the reptile the Woodbine is most famous for as well - a croc. It bears a distal curvature, fine longitudinal striations, and has two distinct edges which aligns with Woodbinesuchus byersmauricei. The longitudinal striations seem to appear on only one side of the tooth while the other side is mostly smooth. I'm not sure if Woodbinesuchus teeth are similar or if the striations continue all around the circumference. Woodbinesuchus was described from the Rush Creek Member which is where I found this tooth. Other crocs of the Woodbine include Deltasuchus, Terminonaris, and Scolomastax (a small paralligatorid with crushing dentition!). Of these I think Woodbinesuchus is the closest, but there must be someone on here who knows better than me. Most likely Woodbinesuchus byersmauricei After only a few hours I had to call it quits. The heat today was killer and the metallic rocks of the Woodbine were not doing my hands and knees any favors as a makeshift oven. I really wish I had discovered this place in the winter or spring . Looks like I'll be watching the weather for a dip in temps before heading back. The possibility for dinosaur material is quite the motivator! Thanks for reading

Found some weird textured rock and some shark teeth where I found big vertebrae which k believe is in woodbine formation. any ideas if this is skin etc? more than likely just fossilized cracked mud. but thought I would see. I found shark teeth in immediate area also. think someone posted on here the teeth I found pretty much with this patterned rock or fossil were saw tooth shark.

All, I’m starting to cut/polish some of the suspect dino/aquatic dino bones found in woodbine formation this year. most are full of pyrite/fools gold and are coated with this sulfuric deteriorating substance. once I start cutting past dusty stuff I seem to hit the pyrite or some other metallic like rock that replaced bone marrow ? Goin through wood cutting scroll saw blades like crazy and going to get some ceramic metal saw blades. I was successful and made it through one bone so far. And included A pic. dino correct on the one I cut all the way through? here are specimens I’ve started cutting the grey pyrite one is very nasty and sulfuric and yes I’m wearing a mask now. Powder is pungent and no telling what would do to your lungs. also here is a tooth I beleive that’s not shark but from some creature from the woodbine it’s broke but here is some pics. Possibly this tooth is from the creature the bones come from and the vertebrae I found in the past at the site. any recommendations in cutting bones and tooth id would be much appreciated. tooth looks nothing like the few shark teeth I found at site. ps I found several of these claw looking things I glued back together. Are they anything bone/very deteriorated teeth/claws or just worm calcified borrows. very fragile and have selenite encrusted on most of em. Have very little knowledge on dino bones etc and don’t look for em just came to this spot looking for Indian stuff and selenite gypsum crystals. fyi cutting and polishing possible bones for a custom knife I’m making and jewelry for daughter and wife.

Hello all! A few finds in some Texas Cretaceous Woodbine Micro Matrix that I could use some help in ID'ing. Not sure if all are just fish teeth or maybe something else? All are around .25 inches or aprox 6 mm. Thanks!! 1. Has a very interesting texture and a distinct pattern on the base 2. Seems to have same pattern on bottom - sadly only half 3. The last one.

Back in August I was catching feeder fish in a wretched little Woodbine tributary when I pulled this out of the muck. It was black and limestone color with thick algae, it was unrecognizable as wood but there were holes and ripples that gave me hope. Hauling this (24 lbs) and my gear & fish was a challenge up a vertical bank and 100 yd walk through thick thorny brush for a 100 lb person, almost left it halfway back to car. After a good scrubbing it still looked like a chunk of water worn sediment and I deleted the first pic of top side, then I tried a new cleaning method I was using on ammonites that were badly stained and got great results. Pictures 1 & 2 show before and after on bottom side but the top was even worse. It won't win any beauty contest I was just happy it was wood. Thinking it was decaying wood and it is full of piddock clams, #5 shows one well. The things in question are 3 & 4, which I'm wondering could they be soft body fossils of Toredo worm? In pics of #4 the black object looks like part of the shell maybe, but #3 looks segmented like a caterpillar which Toredos are not, picture 5 shows one end of it above clam. So what could they be?

I came across this place not too long ago and recently made another trip, I am in love with this site, the colors, the layers, the in your face geology, the fossils, couldn't ask for more. Pocket map says this area is intersection of Woodbine, Grayson, and QAL. Showing in pictures the series of hills running east to west, #1 west end #4 east end. and various shots closer. Forgot to take picture of first hill on western side there was only Woodbine exposure that had layers of intense purple sandstone and what I'm calling snowflake selenite. The far east side was only Woodbine but in the middle hills were several layers of Grayson, top one was more yellow soft and crumbly, below a layer of more white and harder then below that all shades of grey and blue. Along the very top of hills you can see the red Woodbine. Will make separate post for Grayson fossils there are too many pictures, fossils, and questions. This is great learning opportunity so any additional information will be appreciated. Not too many fossils from Woodbine but it's visually difficult for me, everything is red black orange and blends together. Found gastropod, ammonites and various oysters being eaten by selenite but I like the sparkle, and bivalve #6, is this Pinna? Picture #5 was just a single odd place with sand balls. Found what I'm calling chocolate selenite and big chunks of rock imbedded with bivalves and encrusted in white, assuming it's gypsum? I liked the contrast in colors. Including picture of everything found.

This also collected from Woodbine, looks like slickenslide in ways, the texture is on 3 different planes I circled the smallest one. This is so soft to touch you can't feel any ridges, it's so soft I thought the rock would be soft but it's very hard and where there's a chip it appears solid white underneath. It looks and feels like hair it is so fine and soft, so biologic or geologic?

I would really appreciate suggestions on the ID of this microfossil (vertebra?) from a portion of what appears to be a coprolite originating from the Woodbine Group (Cenomanian) of Denton County, Texas, USA.

Collected in Woodbine which seems to be popular lately, never was quite sure what to look for and hope this is it, gotta be leaves right? Not sure what the cylindrical might be.

All of these came from a cliff face on lake Grapevine, no.1 both of these stood out because of rounded shape, plucked from the face of uppermost part of cliff. no.2 there was a thin layer of limonite running length of ledge, all was unremarkable I saw except this piece, thinking impression of plant material? no.3 assuming it's a concretion, thought it was an ammonite when it was cloaked in dirt, found in crevice with some gravels at top of cliff, doesn't look like Woodbine material so stood out, not calcite. Pics are out of order, first one should be last.

My last few excursions have been a continuation of my exploration of the Woodbine. In my experience, it is a very difficult formation to hunt on, so even the smallest of discoveries is a welcome sight to behold. If you have the fortune of finding something there, it is likely to be different and unlike anything from the nearby surrounding formations. My most recent outing took me to an exposure rich with coalified material. The "peat" layer I dug into was extremely brittle and fell apart with minimal effort. Densely packed in was numerous chunks of wood and fragments of leaves likely from the forest floor of the ancient continent Appalachia. If I hadn't dug it out from under several meters of rock myself, I would have thought these things to be modern in age (many of the leaves were just like the dried ones you could find in throughout a yard). I tried my best to spot any bones, but it seemed that only plants were present. I spent most of the day carefully splitting these slabs only to find bits of leaves that immediately fell apart upon exposure. Luckily, I was able to grab a handful of nice specimens that I could take home and consolidate with some paraloid b72. They are much sounder structurally now, though they are still very fragile. I'm not sure if it's even worth trying to ID as many of my specimens are extremely fragmented. However, I think they are distinct enough to see the general shape of the leaves and create a crude snapshot of a Cretaceous forest floor. If you see something you recognize, feel free to share! Here are some photos: Piece 1: Sort of looks like a conifer leaf Piece 2: Piece 3: Piece 4: A tiny leaf Piece 5: This one is actually double-sided. On the front is a large leaf. The other side has a conglomerate of many small leaves similar to the ones found on piece 3. Thanks for reading!

The last month has been a bit quiet for me in terms of fossils. Since school ended for the summer, I've been back in DFW and studying hard for an exam. Thankfully, when test day came, I managed to score well, granting me the time to finally research and take a trip out to a new spot! For most of my life, I've been on top of the Woodbine Formation. I've never perceived it to be particularly fossiliferous as I have rarely come across anything when scouting the ground. However, seeing some of the posts on this forum has since reignited my curiosity about this formation. The Woodbine is a unique place in that it contains material from a coastal environment where terrestrial organisms could be preserved. This contrasts with all of my previous Cretaceous fossil hunting, which were all on nearby marine strata. While I like finding oceanic material, I also value variety and the idea of stumbling upon something unusual like a dino tooth is really exciting. So today, I decided to briefly explore the nearest Woodbine outcrop I could find! I came into today's adventure with low hopes as I know the Woodbine can be unforgiving. Also, it was decently hot and I had forgotten to take my water bottle with me. Scattered here and there were little piles of red rock that I assume had just washed out from yesterday's rain. I spent most of my time getting fooled by little rusty scraps of metal (that reddish bronze color is too similar to the surrounding rock for my untrained eyes). Dehydration was close to pushing me to call it quits when I came across a strangely shaped piece of sandstone. Lots of the stones from this formation naturally exist in weird attention-catching shapes, but I noticed that this one had faint indentations resembling the veins of a leaf. I have never found a plant fossil before so I could easily be mistaking a strangely weathered piece of sandstone for something more than it is, but I am hopeful that this will be a couple personal firsts (my first plant and first terrestrial Mesozoic fossil). For any Woodbine experts... if this is a terrestrial plant, would it suggest that this site could produce dinosaur material? The "veins" are hard to capture on camera, but I think I've done as good a job as I can in the naturally lit photos below. It kinda looks like an oak leaf in my eyes. All insights are greatly appreciated! Let me know if you have any additional questions! Thanks for reading

Yesterday took Rockwood out to Grapevine lake to explore the Woodbine, we went on treacherous hike below spillway that may or may not have been restricted area. Spotted this in place where sun could have bleached it, didn't know what it was without glasses so stuck it in my pocket for not so safe keeping. Didn't make it back in one peice and it's driving me nuts trying to figure out what it came from or if it's fossil or not. I put the peices in order in one picture, the little strip of teeth goes middle.

Hi guys and gals! I found this mystery fossil a few years ago and the people I spoke to at SMU and the Perot are not sure as to what it is. I thought I throw it out here and see what opinions you all might have. Thanks for taking the time to look and try to help. Woodbine Formation : 95-98mya North Texas

So I found this bone. It was found in North Texas, woodbine formation, Ive been discussing this with my friends. They believe its fish. One of the friends believes it might be Ceolocanth since he found a few pieces out here in different locations. I can find pics of anything that looks like it. It has some interesting features: 1.What appears to be enamel or iron scattered around the bone. Its shiny. Looks like enamel but some of the iron out there can look the same 2. It has "grooves" or lines that seem to go along the edges. Could be remnants of teeth, could be bites or claw marks, could be arrow head sharpening marks for all I know. Thanks for the help

Every so often I go kick around at the old AAS, it was on my sight seeing list for Rockwood and we stopped by other day. Finding anything white there is rare, I can't remember any of the fossils from there being white and all the wood there is black. This looks like bone if left with no other choice, but I'm sure I'll be given some
