Greetings, I have only been actively recovering fossils for the past 12 months. Fortunately, as a forensic science teacher, my work schedule allowed me to search approximately 200 days during this time. My interest in Equus is strong based on growing up on a horse farm. After finding my first Equus tooth in Venice, FL, I was hooked. I have been reading: textbooks, The Bulletin of the Florida State Museum, Biological Sciences, and numerous FF members' galleries of photos. I have learned a lot during this journey. I want to share information I have received from Dr. Richard C. Hulbert Jr., Collections Manager, Division of Vertebrate Paleontology, Florida Museum of Natural History, University of Florida. He is the expert on Equus, especially in Florida. Below are some of the responses that I received from him that are "for the good of the cause." From Dr. Hulbert "In each jaw of Equus there are three incisors at the very front, behind them maybe a canine tooth if from a male stallion (most mares lack a canine tooth, if present it is very small and functionless); then separated by a long gap are the six primary chewing teeth. Of these the front three are called premolars, as there are two sets of them through the animal’s lifetime, a set of deciduous premolars that are in use for the first 2-3 years of life, and second set of “permanent” premolars that erupt and come into use as the deciduous premolars are lost. Finally behind the premolars are three molars, the first molar that erupts about 1 year after birth, the second molar that erupts at about age 2, and the third molar that erupts at age 3 to 4. Older members of the horse family, such as Pliohippus and Merychippus, had four premolars instead of three. Examination of the fossil record of horses shows that it is the first of these four premolars that became increasingly smaller and was eventually lost. In order to make comparisons to equivalent teeth among all members of the horse family (and to other mammals), we refer to the premolars in an Equus jaw as the second, third, and fourth premolars. I can tell your specimen is a partial second premolar because the end comes to point when observed in occlusal view. In all of the other five premolars and molars, the front side of the tooth is flat or straight." (see tooth image below with unusual island feature) "I have attached what I think is the correct orientation for this specimen. The formation of the island (what we fossil horse specialists would call a fossettid) is unusual. It is caused by a connection between the metaconid and the protolophid. Just an odd individual variation, not of significance for species level identification. It is seen in Equus more often in deciduous second lower premolars than the permanent ones. But the crown height of your specimen is too great for it to be a deciduous tooth." It isn't often that I find an Equus tooth and can identify it without look at a ID guide. I put much effort to ID everything before submitting an ID request. It is harder when there is an unusual feature on the specimen. I want to give a shout out to @Shellseeker@Harry Pristis for their contributions to identifications and image galleries. Special thanks to Dr. Hulbert for his contributions to Florida Fossil Vertebrate studies. -Regards, Michael

Vertebrae from inland Venice, Florida. Land find. 57mm wide x 75mm high. Side A to Side B measures 52mm. Pleistocene material found in this site. I found a glyptodont osteoderm in this area last week. ID assistance appreciated. I am also looking for a "handy guide" on vertebrae identification. If you can point the way that would help me with several other Vert I have recently found. -Regards Michael

Greetings, Unusual caramel colored tooth recovered from land spoil in East Venice, FL. I understand this tooth is not complete, most likely a lower tooth and not that worn. unusual ridges on the sides. Unlike any other equus tooth I have found. I spent around 15 hours going through the ID galleries from the forum as well as Fruitbat's library. I'm reaching out for help with this one. Additionally, I have recovered an unusual amount of fossils from this 80' x 80' parcel. Iron content in this location results in most fossils colored reddish/brown. I'm hoping the tooth ID will help guide me towards the id of the other animals involved at this site. Dimensions: Length in EQ1 is 4cm. EQ3 photo is 17 mm horizontally and 12mm vertically. Regards, -Michael

Found this almost complete vertebra on the Brazos River near Houston several months ago, missing only one of the larger processes and one of the smaller ones. I initially assumed it was just another horse or bison vertebra which are pretty common around here, but after looking at it again I realized that, although worn, one side is convex and the other is concave like in reptile vertebrae. After looking at some pictures online it bears some resemblance to alligator vertebrae. If that's what it is I would be overjoyed since the only other alligator material Ive found before is a single osteoderm about a year ago. As always, if someone could confirm my tentative ID I'd be very grateful. And an in-situ just for fun:

I'm trying to help someone ID some vertebrae they found recently. They were found in east London, around 4 meters underground in black sticky soil. My first thought was that they looked similar to dolphin vertebrae, and my knowledge of stuff like that isn't great, so any help would be much appreciated! (Actually, I've just realised they're probably from a bison or something similar - I haven't a clue when it comes to mammal verts. The black preservation seems odd though.)

Hunting trip to the Peace River. This is my day "job". The weather is very hot... mid-90s Fahrenheit, little breeze. It is very nice to be standing in a river. With the sun bearing down, I frequently submerge to my chin to cool off. We anticipate afternoon thunderstorms to roll in and soak us. Sometime thunder and lightening add to the experience. Usually there is insufficient time to reach cover before getting drenched. Sooner or later we'll get enough days with thunderstorms that will refill the river from its current low levels. Today is a sorting and photo taking day, when I get to sort, inspect , evaluate my finds, decide what to keep and what to give away. I have already removed the small shark teeth and bones that I donate to schools, fossil clubs, kid's digs, and friends. My wife's goal, after 12 years of this hobby, is for me to keep as few as possible. This has been a magical season which continued yesterday. Here is my final sort... with a couple of hoof cores, a couple of horse teeth, an earbone of a deer , I think, odd looking, almost complete bones that I'll try to identify, and my find of the month, a 70 mm Ursus Americanus Canine. I usually gussy up my fossil finds for their coming out photos.... here are some. The upper hemi is 41 mm, I love the serrations. I find many of the upper roots broken off. Nice to find one attached. A giant Tortoise claw core. This is a first for me. Maybe I just never recognized them. or thought they were a hoof core from some other animal. This one is a Bos or Bison hoof core. It is small at 2.8 inches, so more likely Bos, but not sure anything is deterministic. Small upper horse teeth. The 1st is 26 mm APL and almost seems to have an isolated protocone and the 2nd is 20.6 mm APL and the protocone area is broken away . Then the bear Canine at 70 mm. I think it is lower because of shape and right because of wear facet from upper canine. Certainly is a great memory and a trip maker. It is my 3rd (others in 2012 and 2017). I found it early about 9:30 am. A great day, good friend, the skies opened up around 2:30, a little Thunder but no lightning (at least none close) for these fools standing in the river holding lightning rods.

Frequently see pet hardwood along the San Jacinto river West Fork. This piece does not have the normal shape or tracheid/ray pattern of wood. I don’t recognize the ridges and I see small consistent pores at several faces. The wide depression in the middle reminds me of a Proboscidea tooth. From the right angle, it appears there may have been symmetry to either side. Any feedback appreciated. Thank you all!

I've had this tooth for about a year now after I found it on the Brazos River near Houston last summer. It's definitely fossilized and has the exact same texture and weight to it that all of the other fossils I've found in roughly the same area do. As far as I can tell the whole tooth is still there, but unfortunately the occlusal surface that makes identification the easiest is almost completely worn down, I'm assuming by the animal's age at the time it died. I've tried matching the shape of the top of the tooth with others I've found pictures of, but the issue is the pea-shaped "pinched in the middle" look is very common amongst many mammal species - tapir, deer, sloth, etc. The other thing throwing me off is the single root it appears to possess. If someone could help me with identification or point me in the right direction I'd be very grateful!

Hello dear fellow forum members, I just encountered an offer that made me stop. the Information above is all the seller has, except for the weight of the bone (around 120 g) What do you think this could be? Thanks, J

Hi folks, Found a couple of mystery bones in the brook today, would appreciate thoughts on if these are modern or Pleistocene #1 - some sort of vertebrae, very lightweight so i'm thinking modern maybe deer? #2 best guess is a beaver tooth? unsure on if modern or not #3 fairly long bone, feels much heavier/more solid than I would expect Thanks,

@Harry Pristis Harry, I need your help on an ID and discussion of Florida Calcanea. These are great photos Harry, but I have found one that does not quite fit. It is shorter and wider than the examples. I think that the one I have found here may be Palaeolama mirifica and the camel calcaneum in your photos may be Hemiauchenia macrocephala. What do you think? As always, thanks for your expertise. Jack

Hi everyone! Ya'll where a huge help with the shark teeth I posted, so I figured I'd ask for some help with some of the more unusual stuff I've found at Post Oak Creek. For anyone who doesn't know Post Oak Creek is a small gravel filled stream in north Texas that lots of Cretaceous shark teeth get washed into from the Eagle Ford Group (shout out to ThePhysicist for clarifying the formation!). However a lot of Pleistocene material gets washed in there as well so you get this lovely set of gravel bars where you're finding stuff like crow shark and goblin shark teeth in the same sift as a bison tooth or a horse bone. Anyway here are a few small Pleistocene fossils I could really use some help identifying. The first is a phalange, I'm thinking either Racoon or Bobcat though I don't know for sure. Second I think is a bird bone since it's completely hollow though I have no idea what bird (if it is a bird I'm counting this as finding a dinosaur bone in Texas!) Third is an incisor from a mammal I think. Any insight is greatly appreciated!

A couple of weeks ago I was in Southern Florida with my wife and my sons family for 8 days. My wife, my 7 year old grandson and your’s truly. During this time I was able to get out and collect fossil Pliocene-Pleistocene shells from the Caloosahatchee Formation. Collecting fossil shells is one of my favorite fossils to collect and I love it when I find complete examples. I have been to the Peace River a couple times, and even stopped there on the way home to take a look at it, it was very shallow, there was a group of people sifting, but I did not partake. I do enjoy collecting fossils from the Peace River, but I would rather collect fossil shells. During this trip I did collect hundreds of fossil shells, but I am only posting a few species of complete fossil bivalves, some of these have predatory drill holes in them. @MikeR hopefully you can let me know how my identification is on the following shells, I tend to mess these up. Eucrassatella speciosa Chione elevata Arcinella cornuta Plicatula marginata Carditamera floridana Same as above- Noetia ponderosa macnelli Lucina pensylyancia Solecurtus cumingianus Arca wagneriana Dosinia elegans

Out again today (4th day this week) trying to beat the summer rains. Big focus is bones, two of them. The 1st bone seems to me to be a Calcaneum. The 2nd Bone.

I have a collection of bone and teeth collected in Southeast Missouri caves, usually from gravels in the cave streams. Lots of horse and bison, some camel and very rarely, saber tooth. I have images of two that are uncertain and request some more knowledgeable persons help me with identification. The images have a light blue grid that is one inch. Thanks for any guidance in advance!

Not sure about others, but I realize that I am finding bones that I have yet to recognize, but think might be alligator. Found this nice comparison photo... What is the name of these bones? Are they ribs? Did I find one of them here? A couple more. I think the 2nd photo is a Calcaneum, what is the first and is either this bone?

ø 5cm. Eemian, Pleistocene. Found at Zandmotor, Zuid Holland, Netherlands. -
A member of my monthly bug chat group is trying to figure out what this might be and I offered to post it here to get some ideas. It was dug from a hillside in San Pedro, where clams and crabs were also found. My best guess is the formation is Pleistocene Palos Verdes Sand. They have shown it to the ichthyology sections of the LA County Natural History Museum and seem to have ruled out it came from a fish. My best guess is maybe some sort of coprolite? However, its huge and I also wouldn't rule out some sort of human made artifact.

I was out yesterday... No fantastic finds but a few interesting ones. A Shark tooth, 38 x 23 mm. I thought it was a Shortfin Mako, my friend said giant thresher. Help @Al Dente, @MarcoSr. What differentiates the two... The 2nd is a fish spine. I am used to seeing Catfish spines that look like the one below..... I am wondering and usually pleasantly surprised, when I reach out fro detailed knowledge on any fossil topic, in this case identification of catfish spines.

Found this bone on the Brazos River near Houston several weeks ago. I can tell that it's a humerus of some sort, almost definitely mammal based on its size, but unfortunately both ends are missing making an ID difficult. Any help is appreciated!

hello everyone, I saw this on our favorite website. It is a mammal jaw dredged up off of Newfoundland, Canada. It is likely Pleistocene in age. The piece is approximately 12 cm in length. It is clearly an herbivore, but doesn't look like bison, horse, camel, tapir or deer to me; however, I am still learning to ID my Pleistocene mammals. Any thoughts would be greatly appreciated.

Here is an avian coracoid that I found on the beach in South Carolina. It is from an unidentified off-shore formation that regularly deposits Pleistocene fossils on the shore. I am hoping that someone @Auspex can ID it to genus perhaps. Thanks for looking.
