  1. Hey all, I'll try my best to be brief but detailed in my question, but I'd like it to be a discussion as well, if there is one to be had. From what I understand, the Western Interior Seaway had what appeared to be too many large, active predators for a similar environment to support, especially when one considers how shallow the seaway was. There were the many species of Mosasaurs, with other large predators like Xiphactinus, with the typical western interior seaway sharks as well. This would make me think that that there are two possible outcomes - either an absolutel

    The Rio Puerco Valley

    The Rio Puerco Valley was my introduction to fossils...it immediately caught my attention...lit a match...became a place I am always eager to revisit...search...learn about... ...and in roaming it, have learned about myself. Many of my adventures in the Puerco are posted here, here...here and here...and here. From here on out, my excursions will be shared here. May you find happiness in your hunting. -P.

    Fossil ID Requested

    Good Afternoon! Came across this rock yesterday, looks like a tooth to me, but I'm no expert. Went out during the storm yesterday and got some great points, tools and some coral as well. In the same area I come across mostly those bottle cap shells, coral and oyster fossils. Found in Austin, TX down near the pleasant valley bridge on the east side. Thanks for the help!
  4. 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

    Bone ID requested

    Good Afternoon all! I have found what appears to be a bone fossil. I would love some help if possible identifying it. It was found in Austin, TX in a stream bed. I did the lick test, and my tongue stuck to the porousness, (not that it is scientific, but I figured id add it, just something I read online). Along with the pictures of the potential bone, I also included a photo of all fossils I have found in the same area, coral, oysters and other random shells. All have been found on the surface, do digging, including the bone. The round stone is coral from the end Permian extinction, I know that
  6. Hi again from West KY. Hope these photos are OK. I've wrestled with them for a couple hours now. (LOL) This was found with some others while I was walking a creek in the Jackson Purchase area of KY, Graves County to be exact. This was on the surface, as were the others, all near each other. They look to have been washed out, as the banks of the creek are, in some places, as high as 15 - 20 ft. The other side was cut out in the 1800's to make a railroad track. The ruler didn't come out clearly, but, this measures about 9mm x 7mm x 5mm, weighs 552g. This area is known to have been under wat

    Coniacian Glyptoxoceras?

    Is anyone aware of any Glyptoxoceras sp. in the Coniacian? @doushantuo, I know that you are good at digging up information like this. Can you find anything?
  8. I appreciate all the feed back on my handful of Sulfur River finds and im enjoying being on here and being able to share my love for fossils with y'all. Here is a very special find for me I found it the day after being in a major car accident that I was very lucky to be able to walk away from with only bruises. The Flight museum I use to work for was not to far away from a secret creek that I use to hunt during lunch break, It had earlier formation's of the Western Interior Seaway, Austin Chalk, Kamp Branch etc. I've found several good Ginsu shark teeth aswell as Ptychodus Whip, and othe

    Western Interior Sea way finds

    Ive been hunting the Sulfur River for 10 years and here is a small handful of the Sulfur River finds of mine including the partial Toxochelid I found sticking out of the shale and the 35 pieces of shell and a couple pieces of bone I recovered.

    Mancos Shale Ammonite: Help Wanted!

    I've been looking for an ID for this big boy. So far I've found this site (http://www.ammonoid.com/Prionocyclus.htm) but I'm not sure what I'm looking for to differentiate between them. Could anybody more knowledgeable help me out?
  11. I have been finding a lot of inclusions in a batch of coprolites from the Smoky Hill Chalk that assumed were bits of cartilage. One of the newer specimens from that batch had a piece of the material in question on the surface; enabling me to view it from the side. They look like little teeth, so now I don't know what I have. I have one other specimen that has a couple of the little tooth-like structures intact (one that I posted a while back that has possible Ptychodus tooth fragments). Is this skin with denticles, cartilage, a skull part or some sort of tooth plate? As always, any help is gre

    Possible Goblin Shark?

    It's been a good week for fossiling in New Mexico...found this one in a dry wash in west-central NM. The nearest upstream units were (from nearest to far) kmf-Menefee, kpl-Point Lookout Sandstone and the Satan tongue of the Mancos shale (kms). I've always thought of the Western Interior Seaway as fairly shallow and the shark a deep variety, but the lit says the extant cousin patrols 100m to 1,300m and the WIS was as deep as 750, so there's habitat, I would think. Thoughts? Thanks!

  15. A news article regarding a newly discovered ceratopsian tooth from Mississippi is available at the following link: http://www.wdam.com/story/32562654/paleontologists-make-big-dinosaur-discovery-in-mississippi The ceratopsian tooth from Mississippi is the second discovery of a Late Cretaceous horned dinosaur from Appalachia. We can't be sure if we didn't put enough effort into finding ceratopsian fossils in marine sediments in the former landmass of Appalachia, or if the ceratopsian discoveries in North Carolina and Mississippi could be reflective of ceratopsian carcasses floating out to sea
  16. While doing a search at Paleobiology Database, I was curious to see if I might find records of marine vertebrates from the Cenomanian-Santonian of the Utah, Montana, Idaho, and Arizona because most tetrapods found in the Cenomanian-Santonian of Nebraska, Kansas, and the Dakotas are primarily mosasaurs, plesiosaurs, pterosaurs, marine turtles, and seagoing birds (e.g. Ichthyornis, Hesperornis) and terrestrial vertebrates have been found in the Western Interior dating from the Cenomanian-Santonian interval (e.g. Oryctodromeus, Eolambia, Sonorasaurus, Albanerpeton cifellii, Nothronychus graffmani
