  1. Squalicorax hartwelli (Pathological)

    From the album Texas Cretaceous Shark teeth and Other Marine Fauna

    Squalicorax hartwelli (Cope 1872). Slant length indicated by longest side. This tooth exhibits what is most likely a genetic pathology.
  2. Nj Cretaceous tooth question

    Would this tooth be considered pathological because of this cusp twisting in or is this common.......thanks
  3. Several NJ Cretaceous Non-Shark pathologies

    Hello TFF, I got a couple items from the Late Cretaceous of NJ that seem to be pathological. The first one, an Anomoeodus phaseolus tooth, seems to be very wrinkly and so I deemed it a patho. That is more of a verification as I haven’t seen a pathological one before. The second is an Ischyrhiza mira rostral blade that has a third carina on one of its faces and a slight flattening (flattening better seen in person). This is also a verification as I just didn’t expect to see a patho rostral. The third one is a bit strange. It is definitely a fish tooth. There are prominent growth cracks on the surface & no striations, which supports Xiphactinus. However, the base doesn’t look exactly elliptical (Xiphactinus) or bulging like in Enchodus. But it does look more like X-fish than Enchodus; it just seems as if one side of the base got flattened out, leading me to think that it could be a pathological Xiphactinus. The base also seems to be somewhat hollow (other than the matrix infill). @non-remanié Thanks guys! Anomoeodus phaseolus:
  4. rapp creek hunting

    Tried to get out before the ice storm in search of cowshark teeth (found none and hunted hard). Lots of small sand tiger teeth, including a crooked one and a symphyseal, and lots of split teeth. Lots of drum teeth, (the dull side is more interesting than the glossy side). Four angel teeth that stand up on their triangular base, two whose root is damaged. Two or three mako (broken). Lots of small triangular teeth (dusky, bull, gray? not sure what all they are). Lots of batoid/ skate teeth, but no stingers or denticles. One whole vert and a small disc echinoid. Lots ofsmall 'whale bone' and bits to go through. Not what I was after, but quantity if not quality was good.
  5. Hey everyone, I am posting a pathological Prognathodon sp. tooth with 4 carinae and an odd slight indentation from the Late Cretaceous of New Jersey. I would like to hear any thoughts about this pathology type and if anyone has seen anything similar. Tooth is 17/16 inches. Thanks! Joseph
  6. The first is from the Menard formation the last two are from the Golconda fromation. https://imgur.com/a/8g5R86m I've been away for some time (life keeping me busy). I have a brand new prep room soon I will have other photos of my room and various fossils and rocks. Members that have been around awhile might remember me and to all you new folk I want to say hello (maybe I should have started with all that). Anyway I hope to be able to get back to posting again since things are starting to settle in.
  7. Hey, all! I've reached 1000 posts of the Fossil Forum, and thought I should share one of my small but very cool finds. This is a Vinlandostrophia brachiopod (species unknown), from southern Indiana. It's Upper Ordovician in age, from the Cincinnati Group. I'm not sure which formation it's from, as there are three exposed at the site, and I found it as surface float near the bottom of the slope. It could be either Waynesville, Liberty, or Arnheim. While I have a handful of Vinlandostrophia in my collection, this one is pariticularly cool. Something took a large (relative to the size of the brach) bite out of it, but it survived and healed. This was not a small or simple notch; this was a large part of the shell margin removed. And yet, the critter survived, probably for several more years. There are several growth lines on the healed scar, at any rate. Enjoy! Brachial and Pedicle Valve views Hinge and Aperture views Normal and Pathological side views
  8. I was looking through my shark teeth and I found what I believe is a pathological tooth! The pathology is on the left side just below the root. This is exciting for me because I've heard these are kind of rare. Could somebody help me ID this tooth so I can appreciate it more? It's about .5 inches in length and Miocene in age.
  9. This is my 8.9 cm. (3.5 in.) Spinosaurus tooth, which actually is in surprisingly great shape! (apart from cracks caused by clumsy past owners) However, it is curved (~0.5cm in one direction, and ~0.4 cm off to the side of the previous curve). This leaves me to wonder- how did this happen? My theory is that this Spinosaur either had something HUGE stuck between its teeth that caused them to deform as it grew older; or that a sideways tooth interfered with the normal growth of this tooth, and caused it to grow sideways (to make room for the wayside tooth). The latter is actually very common in humans! (This is why many of us as teenagers had braces, as to prevent our teeth from growing in every direction). I also prefer the last argument (I know, I argue with my self, haha...) because there is a long 3 cm indentation along the side of the tooth, which is exactly where the tooth would have interfered with the room of another tooth. The indentation is likely the blade end of another tooth which was in place when the dinosaur was still alive. The mark is visible on the right side of the tooth in the last image. I just that this was a very unique specimen that I wanted to share with the world, especially because mine is in such good shape for a tooth with almost 6 cm of intact tip enamel, and another three centimeters of root. Does anyone else have some pathological (deformed) fossil teeth they would like to share? Sounds cool! -Fossil sniper
  10. I figured you guys would enjoy a few pictures of this Funky Pathological Meg I dug up in the Peace River a few weeks ago. It was a nice start to the season for sure!
  11. Hello, Found this interesting tooth in Bakersfield, in the Round Mountain Silt formation on Dec 24, 2017. To me it looks like a pathological upper tooth from a cow shark (hexanchus). There seems to be a very small inclusion on the side of the tooth (second photo), but hard to say if it was there when the shark lost it. The tooth is about the size of an American penny coin. Any validating comments or ideas are appreciated.
  12. Has anyone seen this before on a pathological megalodon tooth. I am thinking of buying this tooth from a friend and wanted to hear what the shark to professionals think. Sorry for quality of pictures, I'm waiting for better.
  13. Archaeolamna pathological

    From the album Albian vertebrates of Ukraine

    A. haigi with pathologicaly deformed crown - it is strongly curved labialy.
  14. I will start this out with three really cool patho teeth from the Lee Creek Mine in Aurora, North Carolina. These are all from the Miocene Pungo River Formation. First a small tooth, about 5mm wide 4mm long. I believe possibly Odontaspis Next a tiger shark, Galeocerdo sp., but I am leaning towards aduncus. and last an extremely pathological tooth that I believe is Carcharocles chubutensis, but I label it as carcharocles sp. Lets see what you have.
  15. I recently bought a hooked mako and I just want to know if it is a type of pathologicity. It kinda confuses me, can anyone answer this question?
  16. Texas Cretaceous Shark Tooth ID

    Found this shark tooth in the Atco Formation, what's the species?

  20. Pathological Vertebra

    I picked up this odd vertebra in a stream environment in Austin, TX. It is missing one of the posterior transverse foramina altogether, and shows asymmetrical processes between left and right sides. I am unable to articulate any other pathologies other than to say it just ain't right. So, is this canine? Is the pathology likely the result of a defect from birth? Any thoughts appreciated.
  21. Wondering if Mosasaur get pathological teeth like in sharks & megs? I got these teeth recently and I notice they look a little strange - they look kind of twisted and strange unlike other Mosasaur teeth I have come across. Any idea, if these are pathological or are they just from a certain genus with weird-looking teeth?
  22. Hey Guys, Thought I would start a thread showing some of the more notable finds lately. These are 2013 finds so far. Since there are several pictures, it will take a few posts within this thread. I have to say that most my dives don't include unusual finds. You have to go through a lot of more common material before you find some nicer stuff. I hope you enjoy! Jason This first is a grouping of nicer C. angustidens with the biggest being a little over 4".
