Echinoid urchin spine is a complete guess. I don’t have a clue. Does anyone know what the tan thing with bumps is? It is just over 2 cm long so far. I found it in the Cretaceous, Grayson Formation in North Texas. It has Mariella brazoensis, Waconela wacoensis, a little nautilus, way too many oysters among other things in the conglomerate with it. Could it be an urchin spine? It has tiny, basically microscopic bumps all over it too. It still needs work uncovering. I came to the oyster on top of it and will have to take another approach to removing the oyster.

Dear fellow forum goers, These past few weeks have been quite busy, but that has not stopped me from going on the occasional fossil excursion. A few trips went by since my last posting and I decided to let some trips accumulate before posting again. On these trips I interacted with forum members @Woopaul5 and @frankh8147. The most recent trip was today, 08/12/18, and was somewhat productive. Frank found what we believe to be a part of a mosasaur brain case, which will surely be in his "finds of the year list". I was not as luck but ended up scoring a small point fragment and a jaw section of some fish. There were also some nice quality teeth that I found today. Other than this trip, I scored some nice finds on a few other trips throughout the two months. I hope you enjoy the finds, as I enjoyed finding them, and have a nice day. Kind regards, Trevor Overall Finds Stream Worn Shark's Teeth

i don't know much at all about Cretaceous crocodiles other than there were a ton of them. From what I hear, so many it's difficult to ID even if you have a good amount of an animals fossils, unless it's one of the number of very unique looking species that have a clear signiture. Sadly I'm guessing this fits into the former;difficult/near impossible to ID from just this. *Its a Cretaceous species, from the second phosphatic layer of the phosphate mines in the suburb of Khouribga, Morocco.

Here are some small fossils I found back in the summer of 2017 in Montana up in the Judith River Formation. 1. Small reptile vertebra? (.5 cm) 2. Assorted tiny bones several of which are likely from birds. 2a. Hollow at the broken end (about .8 cm). 2b. Hollow at both ends (1.2 cm). 2c. Hollow at both ends as well, looks like limb bone. (1.5 cm). 2d. Appears to be hollow on both ends (.7 cm).

Hi Everyone, I suddenly have a work trip to the Black Hills of South Dakota coming up next week and I'd like to get out and collect some fossils along the way. I'm driving from Denver to Lead, SD and will be driving north on HW 85 and 18 through Newcastle. I'd be really happy to get a few stops in along the way and any potential information would really be great. Unfortunately, I won't have a ton of time to be able to stop and really dig, so some road cuts or target formations would be super helpful for surface collecting. I'm open to every type of fossil. I know there's a lot of fossils in that section of the state so I'm looking forward to hopefully finding some decent stuff! Thanks! Caleb

Hello, I recently found this bone fragment in Monmouth County New Jersey (Cretaceous) and was wondering if anyone knew what it was. My best guess is a Mosasaur tooth socket but the bone texture looked off to me. For comparison, the last picture is of the fossil in question compared to prior finds which were identified as Mosasaur tooth sockets. As always, all help is greatly appreciated!

Somervell County TX - Fossil Rim area rental with fossils
emtreloa posted a topic in Fossil Hunting Trips
Our second summer trip was up to the Glen Rose, TX area. We rented a great place via Home Away that had a fossil hunting spot. Super convenient when the heat was >110F. We hit the Dinosaur Valley State Park and went fossil hunting at the property we stayed at. Found lots of great cretaceous fossils. Still trying to identify a bunch of them. We found heart urchins, devil's toenails, I think there are some Oxytropidoceras fragments, etc. Oxytropidoceras fragments? Not sure what this is yet. -

Between honeydos this weekend, the Cenomanian Crevasse sang its siren’s song again, tickling my ears, and I was helpless to the call. I will take my buddies with me soon, but the 30 minutes spent solo on site this weekend were pure bliss. On gloves and kneepads I navigated the hummocky surface of the Mainstreet limestone, tapping the pregnant humps with my hand sledge, listening for hollow thuds, and flipping some easy splits. Neithea scallops and Waconella brachiopods were only outnumbered by Ilymayogyra oysters. But I was after a few things a bit less common. One fortuitous blind flip triggered a spontaneous “Tim the Tool Man” chortle as I spotted 2 big whorls of a Mariella ammonite, with perhaps a third diving into the rock. Prep will tell. But this was just a warmup.- 15 replies

Hi everyone, I just returned from a summer in northern New Jersey and had the chance to fossil hunt at the Ramanessin Brook site near Holmdel, New Jersey. We went on 7/28 after a series of heavy rainstorms, so we knew we would have an easy time at finding recently exposed material. We found the usual cretaceous shark teeth fossils, and then perching on the river rocks was this beautiful lower jawbone. I have included a photo of how it was found and the general site area. The jawbone itself does not appear fossilized with minerals and looks quite porous, while I am assuming the dentine in the teeth was well fossilized and has unique hues of blue, red, and brown that are difficult to capture in the photo. The size and specialization of the teeth remind me of a more modern mammal like a raccoon, but I am from Texas and unfamiliar with what is possible to find at this usually marine cretaceous locality. Is it possible that a more recent mammal's jawbone had fossilized and become uncovered in the same area? I am excited to see what you experts are thinking, and thank you in advance! I would be happy to take more photos if needed.

Please help identify the object in the pics below. These were obtained from the WM Browning Cretaceous Fossil park in Frankstown, MS. This was a unique find compared to the typical fossils found there. This does not appear to be a 'rock', but not a shark tooth either. Thanks

I found a couple ammonites this summer that needed very little prep. The first is a Pecan Gap fm Pachydiscus travisi, not remarkable for quality of preservation, but rather for presentation. With both impressions and the steinkern found eroded out together, I have “all the pages of the book”, something that doesn’t present often, in my experience.

Minute fossils (fingers in the background as a scale) from the Campanian of southern Poland. The major element looks similar to bourgueticrinid columnals I know from the site, so maybe a semi-articulated crinoid?

A fossil of a slipper lobster covered in dendrites associated with a shrimp and a fish (Gaudryella gaudryi). One can see that it is a slipper lobster due to the flattened antennas (antennules) found above the carapace. For this reason, slipper lobster are actually more related to the spiny lobsters and furry lobsters, with all three being in the infraorder Achelata. This specimen looks most similar to the recently described species of slipper lobster called Paracancrinos libanensis (Haug) due to its rectangular shape, however I am not sure if it should be labeled as such due to it being much less stocky than P. libanensis and it appearing narrower and longer. The carapace also seems longer in proportion to the abdomen than as described to be in P. libanensis. The antennules (the flattened claw like element) are petaloid in this specimen just like in P. libanensis, however this specimen has much rounder and shorter antennules than P. libanensis. This specimen does not appear to be the seemingly only other described slipper lobsters that I know of in Cretaceous Lebanon, Charbelicaris maronites (Haug), Palibacus praecursor (Dames 1886) and Acanthophoenicides peterpani (Denis) as those three are much more stockier and rounder in appearance, those three species seem to seemingly be more superficially be similiar to modern day slipper lobster. This specimen may just be a variation of P. libanensis, I'd be glad to hear your opinion on the matter. Citations Dames, W.

Hi everyone, I found a Cretolamna tooth that has subtle secondary cusplets in the Cretaceous streams of Monmouth county NJ. I was wondering if this is variation within appendiculata or suggestive of biauriculata maroccana. Any thoughts would be appreciated as always. I hope to take some better pictures soon. The tooth in question is on the left with a typical Cretolamna appendiculata on the right for comparison.
