  1. This last weekend produced probably the best results I've ever experienced while fossil hunting - these last two days will be hard to beat. Before I get to that though, I do want to include a find from the weekend before (since this is the topic of rarity). It was a local find and a first for the species for me. Not only that, but my first real "heartbreaker". It was bound to happen at some point! Sticking halfway out of the gravel, I instantly recognized a large Ptychodus tooth, of either P. marginalis or P. polygyrus - I couldn't remember at the time which of the two
  2. A new polycotylid plesiosaur has been recovered from the upper half of the upper member of the lower Maastrichtian (Late Cretaceous) Pierre Shale Formation of Wyoming: Serpentisuchops pfisterae, the snake-like crocodile face. The interesting aspect to this new discovery is that this polycotylid, contrary to most other known members of this clade (that is, all with the exception of the Turonian Thililua longicollis and Manemergus anguirostris from Morocco), has a elongated neck, convergent on those of elasmosauridae. The pertinent article can be found here: Scott Person

    Polycotylid lower jaw?

    Hi, Saw this and I think it is a small lower Polycotylid jaw (possibly from Manemergus or Thililua) and I wanted to get some opinions on it. It comes from near Goulmima in Morocco and is 42cm in length. Thank you!

    Ozan Formation polycotylid plesiosaur tooth fragment

    Hi all, I got this partial tooth in last week which I bought from a US-based seller claiming it was a mosasaur tooth - though I bought it already suspecting it is not. Having since received the specimen, I can confidently say it's plesiosaur, more than likely polycotylid, as the ornamentation exhibits dense packing of fine striations lingually and a near complete drop-off of striae labially with only some small ones remaining near the base of the crown at great intervals. In a lot of ways this type of ornamentation is reminiscent of that of Jurassic pliosaur teeth. But as the tooth

    Pliosaur or Polycotylid tooth?

    Hi, Just wanted confirmation about whether this tooth from Morocco is Pliosaur or Polycotylid. The crown is somewhat small, but there are still striations on it. I lean towards Pliosaur but I'm not 100% sure at this point. Thank you!
  6. Not sure if this goes here or in Fossil ID but I’ll post here… This is one of my latest online purchases, and one I had to snag because if this is what it’s supposed to be it’s a neat piece. But seeing as I can’t personally verify it myself, I thought I’d post here. This vertebra was being sold as Trinacromerum sp. While I doubt that just a centrum like this is identifiable down to genus, I would like to know whether or not this really is a Polycotilid vertebra. I think it’s likely because it’s a very sizable bone that’s not mosasaur, but just want to check. This fossil is, according
  7. Hi, I have this tooth from the Akrabou Formation in Morocco, and I was told it is a Plesiosaur tooth most likely belonging to the genus Libonectes (An Elasmosaur). I just wanted to get an opinion if the id is correct or whether it could belong to something else like a Polycotylid. The tooth is just over 3cm in length. Thank you!

    Pliosaur tooth? polycotylid?

    On our favorite auction site there is this tooth out there. It's listed as Pliosaur but the thinness makes me think it's polycotylid. It's 1.5 inches. What do people here think? Formation Akrabou Formation@pachy-pleuro-whatnot-odon
  9. I've always been fascinated by the Cretaceous sea and its myriad of terrifying carnivores, many that would've made Jaws look meek. After watching BBC's Sea Monsters, I made it my goal to compile a box of sea monster fossils. I started this journey 10 years ago, and finally completed the box recently. Allow me to present my Predators of the Cretaceous Sea collection, and take you on a journey to the most dangerous sea of all times. The box measures 20.25 inches long. Inside are 24 unique predator fossils. I will introduce them from left to right, top to bott

    Polycotylid teeth?

    Can anyone tell if these teeth are polycotylid? They’re both claimed to be polycotylidae, from the Orenburg region of Russia. I haven’t been able to find out any more specific site info. I’m especially curious cause the 2 teeth have very different details and shapes.
  11. Hi all, I was recently offered this tooth from late Cretaceous of Orensburg, Russia. Most likely Gaisky City District. I can't figure out if it's a Polycotylid plesiosaur or Pterosaur tooth. The overall shape is closer to pterosaur than plesiosaur. However, I am not aware of pterosaur having wrinkling like that, nor do I know of pterosaur teeth being found there. What are your thoughts on this? Thank you.
  12. Dear members of the fossil forum. Some time ago I bought several vertebrae from the Turonian layers of Goulmima, Morocco. 5 marine vertebrates have been found at that site until now. These are Tethysaurus (mosasaur), Thililua (polycotylid), Manemergus (polycotylid), Libonectes (plesiosaur) and Brachauchenius (pliosaur). I want to know if I have a fossil of each of these 4 groups from Goulmima. Therefore I need to know how the vertebrae look of each group. I know the difference between mosasaur vertebrae and the other 3 groups, but which differences exist between t
