From the album: My collection in progress
Placosmilia vidali Mallada, 1892 Location: Lleida, Catalonia, Spain Age: 86-84 Mya (Santonian, Upper Cretaceous) Measurements: 5,4x3,7 cm Kingdom: Animalia Phylum: Cnidaria Subphylum: Anthozoa Class: Hexacorallia Order: Scleractinia Family: Montlivaltiidae -
Hi everyone, I wanted to share my favorite find from the Hell Creek of eastern Montana from the last few weeks. It's overall shape and size suggest to me that it's a hesperornithid vert. The bone is a bit over 3 cm long and around 2.5 cm in height. After some comparisons to Hesperornis vertebrae online I feel that this is the best match. From "Identification of a New Hesperornithiform from the Niobrara Chalk and Implications for the Ecologic Diversity of Early Diving Birds" by Alyssa Bell and Luis Chiappe in 2015 https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0141690

Item 1 looks like a pretty large bivalve, but maybe it's just a rock with a cavity or seed pod? Item 2 seems like a fossil to me, and seems to have the right "look" of a fossilized bone. Item 3 was found in the same spot as 1 and 2, a fallen tree next to a creek in Southeastern Mercer County. Item 4 was found farther south in NJ, near the Delaware River in Burlington County. My 10-year old is convinced it's a fossil - the blue rock is very soft, the matrix seems to be reactive to vinegar. As a beginner with a youngster who is obsessed at the moment with finding fossils, I'd love to be able to confirm we are heading in the right direction - even if we can't positively identify. And if these are just rocks, that's totally fine too The fun is in the hunt and spending time together. Thank you for lending your insight. Really.

Hello all! I managed to secure access to some private land in Gove County somewhere near to Monument rocks. The peoperty has plenty of the chalk canyon type outcrops to explore and I couldn't be happier! I won't make it out there this summer but hope to next summer. I had a few questions that I hoped you all could help with, or point me in the right direction before I head out there. One, I know that the chalk is notoriously difficult to determine stratigraphy in. The chalk I have access to is both higher than and lower than the capstone on Monument rocks. Does anyone know what bed(s) I would be in above and below the capstone layer? I also was curious if fossils in this region are more predominantly found above the capstone layer, or below, or if they were pretty evenly distributed. Secondly, I wondered if there was a good resource that explained how to jacket specimens in the chalk? I have found some strings of vertebrea previously that would look good jacketed and hung on my wall. I would like to be prepared for my next trip out and ready incase I find another decent string. Third, I wondered where is the best place to look in the chalk? As mentioned we have found teeth and vertebrea. These have always been strewn about in the flatter areas. I don't expect to find a Xiphactinous or a Mososaur in my adventures, but I do notice that alot of people mention it requires alot of digging to get them. I take it that means they are looking more in the vertical walls and washes than the flat areas? Can people that hunt there provide some In-situ photos of their bigger finds? Lastly, I wondered if outside of fossils there were any cool rocks or minerals to look out for in the Niobrara or the Rocky Mountain Outwash? I plan on taking my niece out there for a visit and to help her collect fossils for her 4H Geology Project. Here are some photos from her first/only/last year trip out to a location about 10 miles's west of our current access. I can't seem to get the photos to rotate and stay rotated on my phone. My apologies!

With pleasure I want to show you my collection of fossils - it's a work in progress. My first piece is this Lycoptera davidi from Western Liaoning, my brother's gift for my birthday. The plate is 13 centimeters long, the fish 8 centimeters long.

From the album: My collection in progress
Spinosaurus aegyptiacus Stromer 1915 Location: Kem Kem Beds, Morocco Age: 95 Mya (Cenomanian, Upper Cretaceous) Measurements: 7x2 cm Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Reptilia Subclass: Diapsida Superorder: Dinosauria Order: Saurischia Suborder: Theropoda Family: Spinosauridae -
I finally took a trip to the North Sulphur river last week. There have been a couple good rains so I was hoping that would uncover some stuff. The last couple of trips in 2021 were terrible. All muddy and picked over. This trip was still pretty muddy and little in terms of quality mosasaur material. However I went low and found a lot of smaller material. I wonder if the recent muddyness of the river is due to the lake construction or if the river just hasn't had enough rain lately? Is picture 2 an enchodus jaw? I believe the pictures of item 3 are of a really chipped piece of mosasaur tooth. Still never found a whole one this color. Are the pictures of item 4 pachyrhizodus? I have seen people say these are really small mosasaur but I have always doubted this. Any way to identify item 5? Maybe xiphactinus? Item 6 are the few decent mosasaur pieces i found. Is the second one a phalanges bone? Any idea about 7? It is heavily fossilized so i was thinking cretaceous but the shape makes me think of more recent like pleistocene. And my final question. Is item 8 coprolite? Im terrible at identifying the stuff. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

Two pictures of some finds from my recent trip to the W.M. Browning Cretaceous Fossil Site. I'm pretty sure the right tooth in the first pic is crocodilian but I'm thinking the left tooth might be mososaur. Any ideas? Second, the bottom pic is what I believe to be 2 pieces of corprolite, any ideas on this one as well? Thank you

Hey guys, I recently acquired this fossil fish from what seems to be the Araripe Basin/Santana formation of Brazil at a store here in Hamilton, Ontario. Can anyone identify it for me please?

Hi there everyone! I recently came across this beautiful jaw section earlier and I was wondering if there was anyone who could help me identify what animal it’s from. The listing states that it was found in Powder River County, Montana, and is listed as a “reptile jaw”. At first glance through my untrained eye I believed it to be crocodilian in nature. But after a little research I now think it could be Taiidae (lizard). Im still very new to this and I could obviously be entirely wrong so I’d greatly appreciate your guys’ feedback. Thank you guys for all your help and for making me feel like a true part of this community. Cheers!

Hello, this is my first post here on The Fossil Forum. I recently went fossil hunting in the Glen Rose formation near Canyon Lake, looking for echinoids and other invertebrates. I did end up finding a few and tried to identify them myself, but I would appreciate confirmation from somebody more experienced than me. Is the fossil in the images above Heteraster obliquatus? I also found an echinoid that looks to me like Paracidaris texanus. This specimen has foraminifera tests and other bits of limestone still attached to its underside, but I don’t know enough about preparing fossils to work on it right now. Finding these was super fun, and eventually I’d like to learn how to clean them up properly. Any help in identification would be much appreciated!

Hi everyone! I just got a claw in from the Hell Creek and I'm not entirely sure what it's from. I know it's not dinosaur, but I don't know how to tell the difference between turtle, crocodilian, and Champsosaurus (what does a Champsosaurus claw look like anyway, google didn't have any pictures) or even something else if there is a something else I'm not aware of. Locality is Powder River County, Montana. Length is 36 mm height is 15 mm width is 13 mm Any insight would be greatly appreciated as always!

Thanks for any help putting species IDs on these marine fossils from Magoito Beach, Portugal. My best guesses are as follows: 1-12) Oysters, unsure of species 13-20) Clams, original material and steinkerns. 13, 16 and 19 are quite "tall", others rather flat. 21, 22) ?? Possibly a coral? Or crinoid fragments or a trace fossil? 23, 24) smaller oyster pieces 25) a mussel? 26-29) gastropods 30) shark tooth - possibly goblin shark? Sadly fragmented, but has distinctive pair of lobes at the root midline 31) ?? intriguing paddle-shaped structure with a distinctive mid-line 32-38) bonus calcite and gypsum crystals

Hi everyone! I came across this little piece as I was sorting through some of the anthill matrix I brought back from Wyoming's Lance formation. When I first found it, I must not have recognized it as a partial claw as it ended up alongside other odds and ends (fragments of bone, gar scales & other misc. fossils) at the bottom of a pill bottle where I had deposited all of my pickings. This week, however, I emptied that pill bottle to see what was inside in order to organize all the micros I found from this locality (which will get its own post eventually). It's evident to me that this is a claw given it's pair of blood grooves, but it's far and away the smallest in my collection thus far at only 3 mm in length and 2 mm wide. I'm sure it may be a long shot for a definitive ID, but I wanted to see what opinions you all had. And for what it's worth, the flat base and lack of curvature makes it look similar to my ornithomimid claw from the Judith River. These next two focused more on the forceps than the claw unfortunately, will retake these soon.
