Fossil hunting trip to Cap Blanc Nez (Cretaceous of France)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone, Last week after getting lots of recommendations from people I spend a couple of days at Cap Blanc Nez in France to look for some fossils. And while it wasn't to most bountyfull hunt I did have a lot of fun and I was very pleased with the little finds that I managed to do. We had very nice weather, it was sunny and the temperature was just perfect for fossil hunting, and the cliffs and beach (and landscape overall) were absolutely stunning. The fossils in Cap Blanc Nez date back to the Cretaceous and there are deposits from the Turonian, Cenomanian & Albian. I spent a lot of time searching in the clay deposits which lay on the beach. Besides fossils we also found some washed up marine life: A large jellyfish (Rhizostoma sp.) A washed up Harbor Porpoise (Phocoena phocoena) A washed up Small-spotted catshark (Scyliorhinus canicula) We also payed a little visit to the beach at Wissant although we didn't went there to search for fossils but to visit an old shipwreck

While I was sorting through my collection of croc fossils, I came across these Elrhaz Formation teeth I bought 6 months ago and never did figure out what they were. I assume they are croc and not some kind of fish, though I could be wrong. I've never seen these apart from the one source I purchased them from. I've been told they were Sarcosuchus, then Kaprosuchus, then Suchomimus. Pretty sure it's not Sarcosuchus, and the images I can find of Kaprosuchus don't seem to match. Suchomimus, I don't know, but my gut feeling is, no, I've seen dozens of Suchomimus and fake-Sucho crocs, and never found a match. If anyone is familiar with this morphology, any input is appreciated. Locale: Gaoufaoua, Tenere Desert, Niger Last picture is a couple of other crocs from the same lot. One (the robust one on the right) is probably Sarcosuchus.

Dear forumers. Need your help with ID of this ammonite. D about 4cm. Cretaceous, albian.

Hi everyone! Found these two specimens in the Upper Albian Burim formation in Ukraine. Would appreciate any help with ID! 1. So this 1.2 cm tooth is as basic as they get - no carinae, no enamel ornamentation (enamel is there by the way), circular cross section and this really weird apical twist. When I found it in the sieve I thought it was a Polycotylid plesiosaur, but lack of striations is not typical of plesiosaurs. Can't find a large fish without carinae either (Icthyodectids, Enchodontids, Protosphyraena, Pachyrhizodus and other pachycormids all have carinae), although enamel is quite thick and definitely looks more reptilian. Crocs also have carinae. Apparently, Ctenochasmatid pterosaurs can have all of these features, but this tooth is quite robust for a pterosaur. I am confused... For comparison, other stuff from this locality left to right: Icthyodectid, Protosphyraena, Enchodus, Platypterygiine ichthyosaur, Polycotylid, Elasmosaurid tooth tip and Ornitocheiroid pterosaur 2. Well, for this one I am pretty sure it is a teleost of some kind. At first I thought it is a very worn tooth in a jaw section, but the overall shape is inconsistent with fish jaw bones. It seems relatively complete, so it would be great if there is anything diagnostic. (6 cm) @pachy-pleuro-whatnot-odon @Mike from North Queensland @ anyone else

Fossil hunting at or near Fort Hood military base in Central Texas
Creek - Don posted a topic in Fossil Hunting Trips
Spent some time yesterday driving around Fort Hood military base area. I didn't go inside the main base, but there were plenty of public roads and lands next to the base that were not fenced in or restricted. I managed to find few spots that were exposed to the erosion. Most fossils were bivalves, gastropod and lots of broken oxytropidoceras ammos. Due to nature of the preservation most Oxy's were broken. West Fort Hood in the background. Road leading to Fort Hood gate. Exposed Walnut Formation surface. Gryphaeas were everywhere! Collection. This is the biggest Oxy ammo I've ever found in Texas. It measures almost 13 inches.

Quote from Ebert 2014, p. 16-17: “The genus Belonostomus Agassiz, 1834b is one of four genera of the extinct family Aspidorhynchidae Nicholson & Lydekker 1889. The other three are the type genus Aspidorhynchus Agassiz, 1833 from mid to late Jurassic marine deposits of the Tethys (Cuba, France, Germany, Great Britain), Vinctifer Jordan, 1919 from Cretaceous marine deposits of the Gondwana coasts (Antarctica, Argentina, Australia, Brazil, Columbia, Equatorial Guinea, Mexico and Venezuela) and Richmondichthys Bartholomai, 2004 from marine deposits of the Cretaceous (Albian) of Queensland (Australia). The genus Belonostomus is widespread, ranging from the late Jurassic (Kimmeridgian to Tithonian of England, France and Germany) to the Cretaceous (England, Germany, Italy, Lebanon, North and South America) and maybe even up to the Paleocene…” Diagnosis of the genus (amended from Brito 1997 in Ebert 2014, p. 22): "A very slender and elongated Aspidorhynchidae, with a maximum depth (MD) of about 6-9% of standard length (SL). The cranium is also slender and elongate with both jaws of great length. The main characteristic feature is an elongated predentary, which is nearly as long as the dentary. A supramaxilla does not exist. The maxilla is pointed at the ends with a laterally expanded lamella at the dorsal border. Ganoin on the scales is present. There are three dorsoventrally elongated flank scales in the middle of the body, of which the median one is the lateral line scale, which is two to three times higher than long. All fins are reduced in size and have fewer rays than in other members of Aspidorhynchidae." Brito (1997, p. 743-744) mentions a new species of the genus Belonostomus (Belonostomus sp. " 3 ") from the quarry Tlayúa without giving an official name. Identified as Belonostomus sp. by oilshale using Brito, 1997. References: Agassiz L. (1834) Abgerissene Bemerkungen über fossile Fische.- Neues Jahrbuch für Mineralogie, Geognosie, Geologie und Petrefaktenkunde, pp. 379-390. Brito P. M.

Hello I found this piece of sandstone along the Athabasca river just south of Fort McMurray, Alberta, Canada. Since it’s sandstone I’m assuming it came from either the Mcmurray (late barremian or early Aptian) or Grandrapids (Albian) formation although my geology skills are not great. I tried to do some googling on what it could be but I found no results since I couldn’t be specific enough since I don’t really know what I’m doing. Any ideas? I attached an image of the location for fun that I took a while before I found the rock. I found it to the right of the creek thanks

Hi guys, weird question here, I have done some digging but I can’t for the life of me find any decent references to this shark. I guess this is what happens when you fall into the trap of taxonomic collecting lol I’ve been looking at otodus recently and seeing as paleogenotodus is synonymous, it caught my attention. Last question, I wonder if anyone on this forum has actually seen a fossil of this shark? Anyway thanks for your help Also while we’re on the subject of otodus, does anyone have any info or examples of O.limhammensis or O. Poseidoni, thanks again
