    Unknown teleost (?)

    Hey all! This small jaw fragment was in the thousands of fossils pulled out of anthills. I am assuming it is a teleost. Other than several species of sharks, rays, and sawfish, there are pycnodonts, enchodus, and Protosphyraena. This looks like nothing I've found yet. Any ideas?

    Unknown lamniform

    Hello all! I have around a dozen of these teeth. (Found in New Mexico. Coniacian.) The very prominent lingual protuberance should be diagnostic, but I can't find a match. Eostriatolamia tenuiplicatus looks good, but the crown has striations, and these don't. Archaeolamna kopingensis also looked good, but the secondary cusps of this species are oriented away from the main cusp. Leptostyrax macrorhiza also has labial striations. The narrowness of the cusps and crown also has me baffled. Any ideas?
  3. Found close to Paderborn, Germany (Erwitte-Formation) alongside with some echinoids (most likely Micraster cortestudinarium),an ammonite and countless Inoceramidae clams. Marly Limestone Formation of the lower Coniacium or upper Turonium. I was wondering if it could be some kind of petrified drift wood, palm or root?
  4. Good day, all! Can anyone tell me the differences between Myledaphus and Pseudohypolophus? All responses will be greatly appreciated!

    Unknown ray

    Here is another Cabezon taxa that I am having a hard time identifying. Is it Pseudohypolophus? Rhombodus? Myladephus? Something else? Any help will be greatly appreciated! Randy

    Cretodus cf. semiplicatus?

    This is a well worn tooth from the Cabezon fauna. With the lingual and labial plications, I am assuming this is a Cretodus. The narrow cusp leads me towards C. semiplicatus. However, the accessory cusp is not as triangular as I would expect to see from this species. Am I right in my assumption concerning the species, or am I off base? Thanks!

    Ischyrhiza mira?

    Hey everyone, I am trying to identify this tooth. My first guess would be an Ischyrhiza mira oral tooth, since I have a rostral tooth from the same site. But it also looks somewhat like the proposed Onchosaurus oral tooth as illustrated in Bourdon, et. al. (2011) page 39 tooth D. Or I could be completely off and it is some kind of orectolobid. What say you?

    Early Coniacian Tooth ID Help

    I found this in Central Texas Basal Atco Conglomerate with Ptychodus latissimus and Ptychodus atcoensis. It is only about 15 mm to 20 mm tall, including a partially bilobed (?) root and worn tooth crown. Any ideas? Fish or squamate?
  9. Hello all! I have finally finished sorting close to 300 pounds of anthill from north central New Mexico. I recovered (literally) close to 18,000 fossils! Most are identifiable, but there are a few that I can't put a name to. I am going to put up several for your expert analysis (not being facetious, you guys have an enormous amount of knowledge!) to see what you have to say. I will repeat this introduction for each grouping of photos, only changing the take number. Thank you all in advance! This fossil shows the internal structure that I normally see in Ptychodus. But when I flip it ove
  10. The first is a strange tooth whose crown extends far into the root. As you can see on the photos, there is a bulge at the bottom of the crown, and that the root extends up the sides of the crown quite a ways. Any ideas?
  11. This final fossil could very well be a dermal denticle. However, if it is, it is the most robust denticle that I have seen. It is quite large for a denticle as well. Any other possibilities?
  12. Apparently, two of my posts from yesterday didn't go through. So here is Take 2. It is a very small tooth as you can see. It almost resembles a small pebble, but the crown is definitely enamel. A person on the Cretaceous Shark and Marine Life group on Facebook suggested Brachyrhizodus ellipsis. Is there any concurrence here?
  13. Day two of posts. I am posting four more fossils that I need help with. The first is a fragment. It looks like the tooth broke off right before the main cusp. There are two accessory cusps, the larger one looks like it has striations. This caused me to think of Cretodus semiplicatus. However, according to Welton, this shark only has one set of accessory cusps, never two. So any ideas?
  14. The final tooth of today is problematic in that it is a fragment. The main cusp seems to be complete, but that is all I can offer. Any help with this one? More to come tomorrow.
  15. My first thought of the third tooth of today is some kind of orectolobid. But what kind? The cruciform shape is kind of strange. What I am assuming to be the mesial face contains a bulbous protrusion, and the distal face has a concavity in which the following tooth would fit. Any ideas?
  16. The second tooth of today, at first glance, looks pycnodontid. But in the hundreds of pycnodont teeth I have found, I have never seen this type of ornamentation. And the root (as worn as it is) is definitely not that of a pycnodont. Any ideas?
  17. This is the other post that I was not able to find on the Forum (I'm sorry if I am just not finding it) This seems to be an odontaspid of some kind, but it is exceedingly small. Any ideas? I will be posting four more unknowns later today

    Unknown Coniacian selachians

    Hello all. I have found two more teeth that I have no clue about. The first one is very small, orectolobid size, but has a distinct central cusp and accessory cusps on both sides. The tooth is less than 1 1/4 mm in size, and I have never seen a tooth this small with accessory cusps. Any idea as to what it could be? The second one has a distinctive series of ridges on one side of the tooth. Again, I have no idea what it could be. Someone at the museum here suggested a multituberculate mammal, but I have serious doubts about that. The cusp is more selachian than mammal. I will
  21. Hello forum members! With the new Coronavirus raging across the world, I thought it would be nice to start some kind of advent calendar, using my own Squalicorax collection. Everyday I will post one or multiple Squalicorax teeth from one location. Let's see what ends sooner, my collection or the virus outbreak. I will start with the oldest tooth from the Albian substage and end with the teeth from the uppermost substage; the Maastrichtian. The first one is the oldest and also one of the smallest teeth in my collection. Unfortunately it is so sma

    Unidentified shark

    Hey all! Still working on the Cabezon fauna, which looks to be never ending! I have, so far, over 16,000 fossils (mostly selachian teeth) recovered from ant hills. I just went out yesterday and got another 100 pounds of ant hill to go through. Although most of the teeth are scapanorhynchus and cretolamna, there are several other species represented, including some very small orectolobids. I also run across a few that I have not seen in the literature or in other museum collections, so I am going to post a few this week to pick your brains. The first one could be

    Striated both lingually and labially!

    Hello all. Back again with another unknown species from the Cabezon Coniacian fauna. You people were a great help in identifying the Cretoxyrhina tooth that I posted a couple of days ago, hopefully, you can help with this. By far, the most common striated tooth found in this fauna is Scapanorhynchus, of which I have literally thousands of teeth. There are a few that are looking like Leptostyrax that we are researching. And then there is this one. Not only does it have striations on the lingual face, as one would imagine, but it also has striations on the labial face
