  1. Pliocene bone from Florida

    I have found a lot of fossils at a land site in Southwest Florida recently and have been trying to ID them all. After finding a section of gomphothere and rhino tooth I think they are all from the early pliocene. This bone has been driving me crazy though. Its 2 inches long and an inch wide, and any help would really be appreciated.
  2. The winner of the February 2019 VFOTM goes to... Holmesina sp. giant armadillo jaw section - Late Pliocene-Pleistocene - Sarasota County, FL Congrats to @JBMugu!!!
  3. Baby Keichousaurus

    Hi Folks, I wanted to show you a baby Keichousaurus I got for a song at an auction site. It is super tiny and I really like it. It looks pretty unprepped and is raised off the matrix by maybe a 64th of an inch. The matrix measures 2" x 2 3/4" and from nose to tail it is 2 9/16th". Hope you like it. Photos taken with Nikon D3300 with 85mm macro lens
  4. Amber Lizard claw?

    Hello everyone! This one might be hard to identify with sub-par photos – even in person the microscope photos were unclear but you're all smarter than I am. It's about an inch long for scale. Story: I was looking through a clearly un-sorted bag of hundreds of small pieces of Dominican amber (my favorite SO COOL) and saw this tiny piece with what looked like a tiny lizard hand, even though it had three fingers instead of five (maybe they were separated in fossilization). There was no loupe available to check for skin patterns and bone fragments so I bit the bullet. It was cheap so I bought it so I could sleep soundly tonight. I'm thinking it's probably a botanical inclusion at best but wanted to see what you guys thought! Let's discuss. Thanks in advance everyone!
  5. Last summer, on the last day of a long weekend of backcountry fossil hunting around Lake Diefenbaker, Saskatchewan, my friend and I decided to stop our canoe at a beach where on a previous morning I had found a large baculites cuneatus specimen. This beach was an outcropping of a unit of the Bearpaw formation known as the Demaine sand, and dated roughly to the late Campanian. The locality was chock full of golfball to softball-sized nodules, each with a delicate, coalified fossil inside, ranging from crustacean parts, chips of driftwood, to loose vertebrae. It wasn't long before I was looking down at a split nodule containing the symmetrical lines I knew were a skull. So of course, I assembled it together as best as I could, wrapped it in a sock, and we loaded back into the boat to head home. Some typical terrain in the area. The formerly glacial South Saskatchewan River carves deep into the marine clays and sands of the Bearpaw formation: The nodule, rather unceremoniously wrapped in a wool sock: And unwrapped. Note the cervical vertebra just above the posterior end of the skull, and how part of the end of the snout is missing (sorry about the lack of scale bar, there's a photo further down the post with proper scale): I sent a photo to a paleontologist friend, and was quickly referred to the Royal Saskatchewan Museum, who of course were eager to accept the fossil (not to mention that I was technically legally obliged to hand it over, per the Saskatchewan Heritage Property Act... But it's what I wanted to do anyway!). About a month later, my friend and I met with two other paleontologists down at Lake Diefenbaker to deliver the fossil (this time more carefully wrapped in a shoebox...) and to show them the site where we had found it. One long and wet trip in the zodiac raft later, we were there. We assisted in the collection of more samples, this time coming up with an even broader variety of flora and fauna, including a small crinoid, some wood chips with amber, and some more decapods. One of the two paleontologists was excited to suggest that the locality probably represented a near-shore lagoon environment, and that the museum would likely be back to do some more work there at a later date. Unfortunately, we were unable to do so that summer because of the seasonally rising water levels of the lake, which flooded the site, but I've been told that my friend and I will be invited to assist with the operation again this following season. As for the fossil, it has since been delivered to McGill University to be CT scanned. Apparently, distinguishing the bone from the matrix has been long and tedious work, and not much news has reached us since the specimen was delivered some time last September. Here is an individual slice from the CT scan, from near the back of the braincase - notice how porous the bone material is, which is apparently another indicator that this skull belonged to a juvenile: I have been in close correspondence with the paleontologist from the Royal Sask. Museum who will be writing the paper to describe the find, but everything is more or less at a standstill until the work on the CT scan is finished. It's been a rather long wait, but I'm looking forward to its publication - I have been told that the museum intends to hold a press conference after the specimen has been described, and that my friend and I will be credited and involved in the reveal. So far, the museum has kept everything about the discovery deliberately vague, aside from a brief mention in a press conference, which informed an article that circulated around the Canadian media late last summer: https://nationalpost.com/news/canada/scientists-in-saskatchewan-discover-new-multimillion-year-old-fossils It's been an exciting and fulfilling experience overall, and I can't wait to get back into the field, this time with a more meticulous and careful attitude, knowing that there's scientific potential to be had from my future contributions. Anyway, here are some more photos from the lab at the RSM, with scale bar: Decapod claw: Crinoid crown: Thanks for your attention.

  7. Mystery Scapula

    I found this scapula this weekend along the Potomac River in Virginia. It's a vertebrate. That's all I know for sure. Most of the cliff next to the beach where I found it is miocene marine, but the very top is pleistocene terrestrial. The grid is in inches.
  8. Bone

    Just curious what this bone might be. It's not a fossil but wondering what the bone experts think... deer or something else?

  20. I need help with this scale pattern. Snake or lizard? Cenomanian cretaceous
  21. Although lizards are prime material for fakers, i think this tail is authentic. It is an unusial cast fossil. Kind of like a ghost form. It seems that the tail became detached. Much like they do today. This is cenomanian age amber. From Myanmar kachin state.
