From the album: Texas Echinoids, ERose
Bee Cave Member, Walnut Formation, Fredericksburg Group (Albian) Travis County, Texas -
These show up fairly often in the basal pecan gap which has been the focus of my searches recently, nearly all the shark teeth here have the root dissolved so that diagnostic piece is missing but this looks unique enough I'm sure someone has seen something similar, they seem to have a sort of nacre look to the white part so maybe not sharks tooth. This is the largest I have. Microscope pictures with a phone are shaky at best. end on and the back And a smaller more typical example any help appreciated

Unit 3, Upper Member, Glen Rose Formation, Trinity Group (Albian) Kendall County, Texas. This specimen surprised as I had previously understood them to be only found in Lower Member but apparently they range higher in the formation (pers. comm. W. Rader) -

Bee Cave Member, Walnut Formation, Fredericksburg Group (Albian) Travis County, Texas In the lower part of the Walnut formation there is a common variation on the much more common L. rosana that are always small and have a distinctly round apical opening as compared to the typical pentagonal shape of L. rosana. They are otherwise the same as L. rosana and several authors consider L. whitneyi synonymous with L. rosana. -

Comparative photo of the two Glen Rose heart urchins. These are from the "Salenia texana" marker bed at the top of Unit 2, Lower Member, Glen Rose Formation, Trinity Group (Albian) of Comal County, Texas. Note all five ambulacra are depressed in Pliotoxaster versus only the anterior ambulacra in Heteraster-

From the album: Texas Echinoids, ERose
These plates show up in the echinoid marker bed of Unit 2, Lower Member, Glen Rose Formation, Trinity Group (Albian) of Comal County, Texas. They were brought to my attention by JohnJ of the FF and I sent images to Andrew Smith at the BNHM. Smith confirmed/identified them as being in the FAMILY Echinothuriidae. Subsequently Bill Thompson named them Echinothuria mcallae after Linda McCall who had placed specimens in the Non-vertebrate Lab Collection at the University of Texas. Note: there are no known associations of these plates that come anywhere close to a complete specimen. I consider Thompson's species dubious based on incomplete material. He has also named a variety of lantern parts found in those same layers as belonging to this "species" without any actual association. And there are several other echinoids found in the same bed that could easily be the source of the lantern parts. He also has includes obvious cidarid spines under the species, again without any actual association. *the genus Echinothuria is known from the Upper Cretaceous of Great Britain. -

This is a large half specimen of a previously undescribed echinoid from the Glen Rose Formation. Bill Thompson had the genus identified by Andrew Smith of the BMNH and named the species in his 2016 monograph*. This specimen is from Unit 3, Upper Member, Glen Rose Formation, Trinity Group (Albian) Blanco, County, Texas Bill's book is chock full of new species. They (most) are in need of peer review and advanced comparative study. This is one of the few I would actually feel confident with since he had the genus identified by Andrew Smith, who was the man who would know. -

This specimen appears to match the species C. ovatus which was previously known from the slightly older Glen Rose Formation. This one is from the Bee Cave Member, Walnut Formation, Fredericksburg Group, Travis County, Texas. -

These small immature Goniopygus are found in the echinoid marker bed (aka micro zone) of Unit 2 of the Lower Member of the Glen Rose Formation, Trinity Group (Albian) of Central Texas. This example was found in Comal County. -
I found this by Corpus Christi. I am 90% sure this is a mastodon crown but would love some confirmation and then I found this tusk with cross hatching and I don't know if its mastodon or mammoth Any help would be greatly appreciated. Thank you fossil forumers!

Hey Everyone, Went to NSR yesterday. Didn't have a whole lot of luck. Some others I ran into did. I have two pieces. One I think is petrified wood but would like verification. It is not like the normal pieces you find there and rather large also. Other I am thinking might be coral of some type. Thanks in advance for any help.

Hi everyone! This school year has been incredibly busy which is why I haven't been on the forum as much as I'd like to be. However, about a month ago I ordered 3 lbs of washed "Texas Red Beds" (Permian-aged) matrix from PaleoTex - it arrived a few days ago, and I just couldn't wait until March Break to start looking through it (mainly because our March Break has been moved to mid-April - that's way too long to wait!!!) so I began the search last night. I've found a bunch of teeth and bones so far, and I was hoping to get some identification help for some of the larger/more interesting items that I've found so far. Thanks in advance to all who can help! I'll tag a few people who might be interested and/or who might be able to help: @grandpa @JamieLynn @jdp @dinodigger Here we go... Tooth 1 (three views) Tooth 2 (three views) Tooth 3 (three views) Tooth 4 (three views) Tooth 5 (three views) Tooth 6 (three views) Tooth plate !

Im in South Texas, Corpus Christi, which has no Cretaceous or even anything older than late pliocene material. However, architectural landscaping rock comes from the San Antonio Area due to its durability. I mostly check these beds for chert and flint to make arrowheads. One day I found this nodule and I was very interested to know there were fossilized bivalves here from the cretaceous. After more scrounging around I found loads of petrified palm wood and eventually something that caught my eye as bone.

Dear Fossil Forum, We have continued to visit the Brazos near Houston, and it has turned up horse. Teeth, a proximal phalange, and what I think is actually not horse, but a tapir calcaneus! My latest find is a vertebra, and it looks like thoracic vertebra 18 (T18). But, in comparing it to a photo of a modern horse example, the facet for rib attachment is smaller in proportion, and lots of other details look a little different as well. Does anyone know of good resources for researching fossil horse ancestor vertebrae? Or know if there is variation in contemporary vert structure depending if mule, donkey, etc? I also do not have a good sense of scale. Photos attached. As always, thanks for looking

Got out to my favorite spot for an hour before dark last night. Started to walk down a small slope and saw it. I swear I looked back and away three times not believing what I was seeing. I have found a few monsters in this creek including a few over the two inch mark but could instantly see this one is crazy special. This is by far the largest Cretodus I have ever seen. Not only does it break 2.5 inches but if there were a record for weight, this may be the top. Thought my plesiosaur vert I found in January was my find of the year, think this may have just moved into first place.

I am having trouble putting a label on this cephalopod from the Upper Pennsylvanian, Graham formation, Finis Shale member, from Jacksboro Texas. The conch is crushed on the anterior end which distorts the apical angle but the intact posterior end shows an angle of around 12º and the cardinal ratio is about 2. My first thought was bactrites but if that is the siphuncle it appears to be very near but not quite in contact with the ventral wall, which I thought was a requirement for the whole subclass. It looks a little like the “doubtful” genus Cylobactrites with the foldlike ribs and missing ventral lobe, but the treatise shows those to be Mid-Denonian. Maybe the ribs could be described as annulations and the siphuncle as subventral making it a nautiloid like some Brchycycloceratidae but B. normale and B. curtum are all I see on the fauna list for the site and they have much large apical angles at around 22º and 40º. Any ideas?

I took advantage of the nice weather on my last couple days off and went to a couple sites around town, in no particular order here's the most interesting things I found. First a worn ptychodus anonymous tooth from the eagle ford shale. next what I think is a pachidiscus travisi from the basal pecan gap chalk and a half of a graptocarcinus texanus carapace from the buda formation in a location I had never found anything particulary interesting before. Quite worn but still recognizable And while normally one finds echinoids and ammonites in the georgetown this time I only found what I think is a partial pycnodont tooth

Hi everyone, I'm trying to id some very small shark teeth for an independent research paper I'm writing and am a little unsure on my ids. I took some photos of some typical specimens and was hoping to get some feedback. The scale bar is mm. I put what I think the species is with each group of photos. Any feedback and tips for differentiating these species would be greatly appreciated.

Today is my 50th birthday so I wanted to select my fifty favorite fossil finds to present. But....because I am obsessive, I couldn't settle on just 50. So here's 150. My favorite 150 fossil finds. And there's still more - but then it would be 250 or 555...I don't know. Anyways, enjoy. Mostly Texas, some from Utah, Florida, North Carolina, New York and England (denoted by the state initials or UK). Almost all were found by me, except about 4 which were gifted to me. I did actually narrow it down to 50...initially. But then I had to do pages for the rest of them because I didn't want them to feel left out....

I found this chunky bone end fragment in sandy gravel matrix, Pleistocene era. This may be a chunkosaur, but since there are at least a couple of possible identifying characteristics here, I'm hoping that someone with more experience than I have could help me narrow this down. Didn't seem to fit calcaneus or astragalus, but it does show a groove and two points on one side that are pretty well defined. Image One: Flat face Image Two: View of taller side Image Three: View of shorter side

The waterways are down enough to hunt some again in my area. This is a find from yesterday, sandy gravel matrix in the river. Pleistocene era. I'm thinking it looks like a spinous process from a large vertebrae, but I'm not positive. I'm also unclear on size differences and other distinctions that could help me narrow down the species. I was thinking possibly bison or camel. Any ideas would be great.

Found in Creek stuck in wall sediment by Corpus. Was next to arrowheads I will do burn test soon but it might be only 5 - 15,000 years old so I dont know if it will pass
