  1. 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!
  2. 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.
  3. 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
  4. 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!
  5. 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?
  6. Whale Ear Bone

    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.
  7. Fossil whale bone (specific bone ID)

    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.
  8. Maybe ancient mammal bone

    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!

  13. Vacation Fossils

    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:

  17. I don't read a lot about hominid fossils but I try to keep up with general knowledge of recent finds and discussions. Sometimes, the various science magazines will publish a special issue on the subject and I try to pick up a copy. The September issue of Natural History is devoted to human origins with a few articles with even one on the ancient primates of the Paleocene and Eocene along with a reprinted column by the late Stephen J. Gould. I haven't read it yet but leafed through it (nice artwork and fossil photos in it). I had seen it that month at a local Barnes & Noble but the last copy was all bent-up like an accordion. I looked for it at another store but couldn't find it. I went back to pick up the beat-up one I had seen but it was gone. After hunting around the magazine website, I found that back issues were available so I mailed away for it ($7 including shipping). Ten days later, it arrived. In case anyone else is interested, here's the link to page with the back issue address - just scroll down to it: http://www.naturalhistorymag.com/contact.html

  19. Bird ?

    I was walking in the beach (Sesimbra- Portugal) and I just found this nice fossil. I just know that is from Cenozoic age. Can anyone help me? thank you in advance best regards PG
  20. Just got back from the Orlando Fossil Fair 2018, I bought some nice fossils but many were not identified and I want to confirm ID's for ones that were. There's a lot of fossils so I'll label each one with information and my own opinon on them. All the fossils shown are allegedly carnivores and found in the Suwannee River in Florida (excluding two of them). The furthest on the left will be #1, and the furthest on the right will be #4. I'm not convinced that 1 is a carnivore but besides that I don't have any hypothesis on what the others could be. The left one in this picture is 5, the one on the right is 6. Five reminds me of a bear, and I don't have any idea what 6 is or if it's even a carnivore. The tooth will be 7 the jaw will be 8, both are allegedly dire wolves (they're not associated) from 'Northern Florida', I don't have an exact locality unfortunately. I suspect these both belong to dire wolves. The furthest left will be 9, and the furthest right is 11. I suspect 9 and 10 to be racoon teeth, but I'm not sure if racoons are found in the Suwannee river. At first I thought 11 was a canid, but after looking at it for awhile it looks more like a feline. This last specimen will be 12, right now I'm stuck between a primitive canid (possibly leptocyon) a feline, or some sort of fox. This specimen was also found in the Suwannee, like the rest except the dire wolves. If you need more pictures I can take some and post them within the hour. Thanks in advance!
  21. Mammal Jaw Fragment

    I obtained this mammal jaw at the Colorado School of Mines Geology Garage Sale a couple of years ago in a box of rocks that had been detached from their labels and so lost much of their scientific value. That made the box of rocks cheap, but it means that I am on my own to figure out what all of it is and have no location information at all. I am hoping that someone on here will maybe recognize it enough to steer me in the right direction for even a higher taxonomic level identification. I am more than happy to provide photographs from any additional angles that would be helpful so please just ask! Any thoughts are greatly appreciated!

  24. In the current (July-August 2018) issue of American Scientist magazine there's an article on champsosaurs. Anyone who's collected Late Cretaceous fossils in Montana, the Dakotas, Wyoming, or southern Canada has probably found a few. You tend to get just a paragraph or two about the group in mainstream science articles about animals that survived the K/T extinctions but there's a whole article about them. Check out your local Barnes & Noble if you don't have online access.
  25. So, I found this today in the Paleocene Aquia Formation of Maryland. Obviously it can't be an ammonite, because they were already extinct. It's a Nautilus steinkern, right, not some sort of gastropod? Thanks! Matt
