I got this amber when I was a small kid. It used to have a tag with its source listed, but it's been lost for 12+ years, and I can't for the life of me remember what it said. Looking at it, does anyone know whether it's more likely to be Dominican, or Baltic? It is yellow, but has a slight gold tint, and is slightly translucent. There's a couple of small buggos in it.

Hi all, I'm recently retired and I live in NW Wyoming and was wondering if anyone could shed some light on these specimens? Im particularly interested in the big rock/fossil? at the top of the picture. I found all of these on the surface in a sandstone, drab mudstone formation. Possibly Eocene, Paleocene time frame based on some quick geologic research. Looks like a foot to me but I suppose it could be about anything. The other items were found in the same area with the larger one. The area would have once been the near the edge or boundary of Lake Gosiute an/or the inland seaway I think. I have enjoyed reading some of the posts, seems like a good forum! Thanks, WyoProspector

I have been photographing my collection of Pliocene gastropods from the Southeastern US, but I realize that I will never be able to completely picture every specimen within my collection. On a Facebook page about fossil crabs, @MB has been showing individual drawers within his collection. I like what he is doing so I thought I would do something similar here with drawers within my collection of fossil gastropods. My display collection is organized chronologically, the first seven drawers being Pleistocene. Since many of the formations within the southeast share species and I have limited room within my drawers, I display the two best specimens from any formation within the group so there should be no duplicates unless the same species from different formations demonstrate noticeable variation. Within my Pleistocene drawers, the following formations are represented: Upper Pleistocene Fort Thompson (Florida) Flanner Beach (North Carolina) Chibania (Middle) Bermont Formation (Florida) Calabrian (Lower) Caloosahatchee (Florida) Nashua (Florida) Waccamaw (North and South Carolina) James City (North Carolina) Gelasian (Lowest) Chowan River (North Carolina) Pleistocene Drawer 1 contains the Families Fissurellidae, Calliostomidae, Turbinidae, Epitoniidae, Eulimidae, Cerithiidae, Potamididae, Turrritellidae, and Vermetidae. Quarter for scale.

Hello all Up for trade is this set of South-American teeth. It includes 11 Chilean and 4 Peruvian teeth. The C. chubutensis, Isurus desori and Carcharhinus cf. brachyurus (the last three are on the right side) are from Peru. The others (Megachasma pelagios, C. hastalis, Carcharhinus cf. brachyurus, Isurus retroflexus and a fish tooth labelled as dog fish (not sure if correct) and some unidentified teeth. The C. hastalis is just over 2 inch. The Megachasma pelagios is around 2 cm. The C. chubutensis is just under 2 inch and has a crack in the root, but is broken. More precise location is available with every tooth. I prefer to trade this as a set. Also up for trade are these partial teeth from the Santonian of Israel. Certainly an unusual location. What do I want in return? Squalicorax teeth from unusual locations, any Kem Kem stuff I find cool (teeth, bones, scutes, unknow stuff), reptile, amphibian or dinosaur stuff, Mosasaur teeth from Unusual locations or I'm open for any offer I like Due to Corona I can only ship after the end of the lockdown.

Hi, Even in this hard times of corona virus outbreak I couldn't resist the urge to visit again a cave that I found a few weeks ago, but couldn't explore it fully. So I went again and this last time I went in the cave I found a great number of bones scattered around the cave. I think they are probably modern, but it is weird because the cave isn't very easily accessible for animals since it has a few big drops. I found this tooth in a small ,,room,, which was barely big enough to squeeze in to. In that same place there were a small broken skull and many bones, but this is just one of the many places with such bones. At first I even thought that some explorers ate a chicken or something like that in there, but the bones are just too many and THIS WOULD HAVE BEEN A CHICKEN SLAUGHTER FEST. I would be glad to hear your opinions on what creature is this toot from and if it is modern or ancient. The color I guess would suggest modern but i am no expert on how are bones preserved in caves and sadly I have no information on the age of the cave. I hope you are all fine and the virus never gets to you!

Hello everyone, I have decided a while ago that I would focus on collecting Paleozoic material, because of this there are quite a few fossils I have that I purchased a long time ago and do not have an interest in keeping, these guys are not that special and I am not looking for much of anyone even does want to trade with me, but I do prefer Paleozoic material. I will post what I have here. 1.Lebanese shrimp fossil Cretaceous GONE/TRADED 2. Geocoma carinata I believe from the Solnhofen 3. Chunkosaurus 4.some cretaceous teeth, spinosaurus, Squalicorax, scapanorynchus, enchodus 5. Some gastropods 6.otodus obliquus Morocco eocene

Hi my name is Elias and I am new to the Forum! About a week ago I found a large piece of what looked to be fossilized bone, on Folly Beach SC. Upon further examination I noticed that it seemed to have a solid light gray center surrounded by a ring of bone. Further research has led me to believe this may be a chunk of Mastadon tusk, however the specimen is so beaten up it is hard to identify any Schreger lines. I am much more experienced in Cambrian and Ordovician fossils, and have just recently begun exploring fossils of the Pleistocene Epoch. I would appreciate any help on identifying what this is, and can send more or clearer photos if necessary! Thank you so much for your help! Elias

Help request! Seeking diagram of scleractinian architecture through time
pefty posted a topic in General Fossil Discussion
I recently saw a wonderful diagram showing the fossil ranges of various scleractinian coral architectures, or at least the ranges of genera typical of those architectures. But now I can't seems to find it again... The diagram included images of the various coral growth forms and was simpler than but otherwise similar to this: If anyone knows where I might have seen such a diagram, please post the url here -- thanks! -
In recent years, I have become just as interested, if not more so, in non-dinosaurian prehistoric large reptiles than in dinosaurs themselves. Especially giant reptiles of the Cenozoic. Right now one of my prize pieces is a partial Megalania vertebra from Australia. However, I would like to acquire more large Cenozoic reptile fossils in the future, such as sebecosuchians, palaeophiids, giant crocodiles and giant tortoises. What material of this kind have TFF members seen available commercially? Would also like to have information on Triassic non-dinosaur reptiles. And Palaeosaniwa, Hell Creek's Komodo dragon.

Any help on identifying what these might be would be great. Found near Reno, Nevada in an area stated as being from the Cenozoic period. They appear to be bone to me and I did use the "stick to tongue" test and they do stick to my tongue for a second. Thank you for any help or a push in the right direction for me to find out more specifically what they are. I will add more pics in comment section.

I saw this tooth at a gem and mineral show a few years ago. Unfortunately, it didn't have a label. Normally, I pass on fossils with no info no matter how cheap and intriguing they are but it was unlike anything I've had in my collection so I bought it. I just found it again this year while trying to clear and clean up some space. It's a mostly-complete crown, perhaps a lower molar, with perhaps some root but the base of the tooth is almost completely obscured by restoration which appears to be plaster. A little plaster was also used to restore part of a cusp and part of a side. The plaster appears off-white to a yellow-orange against the brown enamel in the photos. That indicates it's an old collection piece as almost nobody uses plaster anymore, various types of putty having been the preferred material for at least the past couple of decades. It's about 1 1/2 x 1 11/16 inches in occlusal view and the crown is about 5/16 to 11/16 inches high. I showed it to a fossil dealer with a lot of experience with a range of mammals. He thought it could be something unusual from the Eocene and more likely the later Eocene. I think it might be an early gomphothere tooth and one most likely from North America (as it came out of a private collection in California but that's really just a guess) which would make it Middle-Late Miocene in age. I guess it could be some kind of anthracothere. I don't know. I was wondering what any of the "mammal people" think of it. @fossillarry @Harry Pristis Jess

Hey Everyone - I hope someone can provide some insight and help me identify this fossil. I would really appreciate it! I found this strange looking tooth (at least I think it is) a few years ago in San Antonio, Texas. It feels and looks like a rock as far as texture goes but it's shaped very similar to an animal tooth. I've attached photos for reference and labeled each one: Front Back Side Front Height - 5 inches (12.7 centimeters) Front Width - 4.5 inches (11.43 centimeters) I've also attached a Geology Map of Texas which outlines where rocks of various geologic ages are visible on the surface of Texas today. On the map, I circled in yellow the location of where San Antonio, Texas is for reference. Hopefully it can provide more insight for you. I'm not even close to a geology expert but limestone is very prominent in San Antonio. The city is also home to The Edwards Aquifer which may or may not be useful. I'd be happy to answer any questions and I can also take additional pictures if needed. Looking forward to hearing back from you all!

Hello everyone, I have enjoyed trading fossils with people on the forum so here are two more I have to offer. This is a nice pair of Thalassina anomalas from Australia, the larger one is missing most of the tail but has pretty nice pincers which are not commonly found intact. Their sizes are around 8 and 5 cm. The smaller one also has an incomplete tail. I myself am looking for Paleozoic fossils especially trilobites. Thank you, Misha.

I watched a show on PBS last night, "When Whales Walked: Journeys in Deep Time." I just happened to notice it on the guide about 45 minutes before it was on. It is actually about more than the evolution of whales, the group having four-footed Early Eocene ancestors. There is a long segment roughly twenty minutes long each on crocodilians, birds, whales, and elephants. I thought it was a good show overall with interviews of researchers I know from their technical articles ( Hans-Dieter Sues, Philip Gingerich, Emmanel Gheerbrant, Christian de Muizon). However, each segment was also a little light on content for the topic and one was especially unclear. The one on birds made it appear that Deinonychus was an ancestor of later birds. They should have showed a chart showing when it lived in the Cretaceous with Archaeopteryx and the Liaoning birds millions of years before. There was a quick view of a family tree that seemed to illustrate that but it went by in a second or two. The segment on whales showed a lot of footage of modern whales and some great background on the "first whale," Pakicetus, but it didn't show any of the whales described in the past twenty years. It just mentioned that there had been recent discoveries. I thought there should have been at least a quick look at Ambulocetus and a few of the increasingly more marine-adapted forms that lived before Basilosaurus. They pretty much jumped from Pakicetus to Basilosaurus to the divergence of toothed and baleen whales. I think they could have spent the two hours just on the whales just as the title of the show led me to believe. I liked the segment on elephants because just as I was expecting the show to skip the earliest known members of the group, they go to Morocco and then talk to Emmanuel Gheerbrant who described Phosphatherium, the first probiscidean, which is known from the same early Eocene phosphate layer as a lot of the shark teeth we see at shows are from. Other extinct forms were descussed as well. Here's a link that takes to an online notice and website: https://www.pbs.org/show/when-whales-walked-journeys-deep-time/ Jess

Recently I’ve found some strange fossils from an area in Simi Valley (Southern California). I had thought there were only shells, but turns out there is vertebrate material! Among other fragments, I found a couple big whale vertebrae as well as this piece here that I am unsure about. I’ve seen some mentions of fossils from smaller marine mammals like dolphins and pinnipeds, maybe it’s one of those? Unfortunately there only one end present, so I’m not expecting to get anything too specific. The formation is about 5 million to 11 thousand years more. Hopefully I can get some more interesting things from that spot. Thanks!

I was on a hike on top of a hill (about 700 feet in elevation) in Chino Hills (roughly 50 miles inland from the Southern California coast line) and I picked up a few loose sedimentary slabs and looked under them. I found this clear fossil of a seashell. I’m wondering how old it could be? What period was a sea covering Southern California and this high up from sea level?

I found this in a creek in the Charleston, South Carolina area where I often find sharks teeth and whale bones. I believe the site is Oligocene/Pliocene. If found anywhere else, I would have assumed it was a piece of gravel and tossed it, but it does look a little strange. Perhaps someone with more experience in the Cenozoic can help with the ID. The item is about 3 inches at its longest dimension. Like I said, I am thinking tumbled gravel on this one, but figured that I would check before throwing it in the garden.

Hello all, So i've recently come into the possession of this chunk of bone, and based on the size, porosity, and locality (York River State Park) I believe it's a whale bone (Miocene-Pleistocene in age, likely a mysticete). My question is, which bone exactly is it? It seems to have some fairly distinctive features that seem to lend towards identification, but after around two days of research i'm stumped. I'm thinking it could be anything but some vertebral element, but i'm not sure. Any help is greatly appreciated.

In addition to the possible orthocone fossil I found in the same creek, I found this mammal bone. I live about ten miles as the crow flies from Big Bone Lick State Park in Kentucky. I live on a cattle farm (have had horses on the farm before as well spanning at least 50 years). This bone struck me as looking quite old due to the coloration and the slight erosion on it. With me living on a cattle farm, I’m leaning towards it being some sort of bovid bone, but want to know your all’s opinion. Thanks!

Bought this fossil bone from an old man, not sure what it is, guesses?

Our first full day of sun, sand, and surf in Jamaica bumped up against some fossils, and pseudofossils. In this area (St Ann’s Parish), more than 75% of the rock here is limestone spanning from the Cretaceous to periods in the Cenozoic. Not far from me is the Blue Mountains, the highest altitude on the island (we’re planning on a day trip to see the coffee cultivators and a 12 mile downhill bike ride). Given the abundance of limestone, it is no surprise that it features prominently in a lot of building material. Here is some fossil coral in some large, raw blocks:

Howdy from the frontier country of New Mexico! I'm Tammy. I stumbled upon this forum while trying to categorize a very large collection of interesting fossil specimens collected in the mid to southwest of New Mexico, by our daughter Carol (an avid fossil collector). During her last visit we separated some of the largest specimens, revering some more than others, discussing the cosmos and the earliest life forms on planet Earth. We recalled that Carol collected rocks as souvenirs from vacations. On a vacation to Minnesota, Carol collected a '(flat) rock'; it was a decade later when she realized it was actually a prehistoric tool! I'm positive that's what started it all! I hope you can forgive our lack of 'technical' terms and a few run-on sentences now and then, as we attempt to analyze and understand this collection. I'm off to read and learn! Sincerest gratitude, Tammy
