As we haven’t been able to get out to the coast collecting we’ve been going through my daughter’s collection and trying to label her finds in the same way as her fossils from various shops. Many have already been identified here, but here are a few that I was hoping to get help with. I know all but one are ammonites but I was hoping for more specific than that. All are from the stretch of Yorkshire coast from Staithes down to Saltwick Bay Thanks in advance

Hi Guys My son found this neat little fossil on the beach at Charmouth, Dorset, U.K. We had no clue what it was until we had it looked at by an expert at a fossil roadshow. We are considering removing some of the limestone matrix that hides some of the teeth. Do you think we should attempt to remove some of the matrix or is it too risky. There are several Hybodus shark teeth in what appears to be part of the jaw bone. With what I think is a limestone, type matrix covering some of the fossil. None of the teeth can be seen in full. I have some experience using fine hand held electric carving tools. And it would be very interesting to see more of the teeth. What do you think ? Thank you for looking at this for us. Matt

Good afternoon folks. I have what was identified as a Sauropod coprolite (1 of 5) from the Morrison Formation, Henry Mountains, Wayne County, Hanksville, Utah. Jurassic period (Per the seller's description). I purchased this back in 2000 and am requesting a verification so I can ensure my ID card is correct. All help is appreciated. Measurements are 8.5Cm W, 6.0Cm H, 4.5Cm D.

Sometimes I find things in nature on my own, sometimes I purchase things. This I purchased at a fossil and mineral show. I believe it's important to support such shows to keep them going. This is a nice ammonite, I guess some 165 million year-old I suspect this one is from the Jurassic period--it was collected in Madagascar. I've brought this little guy to some small classes I used to teach. It is about 9 inches across.

Hi everyone, I recently found this tooth in some material i collected last month and I’m pretty sure it’s a tooth, maybe mammal. Can anyone ID it to a species or genus level? It was found in the bathonian forest marble formation of Dorset, UK. Thanks .

hi guys and girls i would really appreciate some help identifying these ammonites that i've had sitting around for a while now the first one comes from the inferior oolite of burto bradstock and the second could be lissoceras oolithicum,??? oborne wood, sherbourne. dorset, jurassic, inferior oolite, polygyralis zone

Hello, I recently got a hold of this tooth from an old collection in the UK. I am unsure if this tooth wouldve come from a ichthyosaur or a pliosaur since the root is absent and I'm not expert in this material, so any feedback that help figure this tooth out is appreciated.

Hi I’m new to this forum. My son and I love fossils and we found a few interesting ones on a recent trip to the Jurassic south coast of England. Can anyone help with the identification of this fragment of bone we picked out of the sticky, Jurassic, Oxford Clay? The bone fragment seems to hold the remains of a small tooth? Its only 2.5cm long in total. Thanks Matt

Hello, Went fossil hunting in a famous Swiss Jurassic Location, the quarry of Liesberg. While cracking some rocks found what seems to be a crab claw. Can anyone help me identifying it? I was not aware such fossils could be found there, is it common or rather rare? Thank you! Cheers, Romain

Hello all I was wondering if any of you could identify this very tiny (1mm) ammonite sitting on top of some Dactylioceras athleticum from the Jurassic of Schlaifhausen, Germany. Can this be a juvenile stage of the same species? I know nothing about the different lifestages of ammonites. Looking forward to your answers. Edit: does someone knows the size of the smallest ammonite recorded?

Dinosaur stomping ground in Scotland reveals thriving middle Jurassic ecosystem
msantix posted a topic in Fossil News
Dinosaur fossils from the mid Jurassic are generally rare but the Isle of Skye in Scotland has revealed fossils sites preserving around 50 footprints on ancient coastal mudflats. The footprints suggest that Stegosaurs and possible ancient cousins of duck billed dinosaurs were living in the Isle of Skye around 170mya along with large Sauropods & Carnivores, suggesting a high diversity of dinosaurs from the mid Jurassic in Scotland. https://www.sciencedaily.com/releases/2020/03/200311140536.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Ffossils_ruins%2Fpaleontology+(Paleontology+News+--+ScienceDaily) The Journal article is listed below and is open access https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0229640 1. dePolo PE, Brusatte SL, Challands TJ, Foffa D, Wilkinson M, Clark NDL, et al.

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA- 5 replies

Hi everyone! Oxfordian again This time it's the turn of small shells from Peski Quarry, located some 80 km south-east of Moscow. It's something like the Moscow region's Jurassic gastropod heaven. For some geologic reasons, ammonites do not get preserved there while little gastropods and bivalves do. It's also the only place dinosaurs were found in the Moscow region. As of today the continental sediments are depleted, but the marine ones are stil abundant. The quarry extracts Carboniferous limestone, removing Callovian marl and Oxfordian clay. The clay is then discharged in open piles - small shells of exceptional quality are washed up during rains. Below are pictures from two trips: one in winter (with snow) and one recently. To get to the Jurassic part of the quarry fastest you have to go through woods along a small river:

Hi everybody! These two are my second and third fossil collected in the wild, I'm 94% sure they are both coprolite......what kind? That's where my assuredness plummets. Both were found on the south side of the Isle of Wight on the beach at Brook Bay. I was there in late November of last year and did nighttime search using a UV flashlight. There were some brutal gale force winds, so I was only able to muster enough manliness for 20 minutes on the beach, I made a few discoveries, but these two are choice. I located the lighter coloured one because of uneven fluorescence and located a surface bone fragment, and the dark one because of it's deep purpl-ish glow and unique shape. The lighter one I believe is a crocodylian coprolite, the other I'm sure is coprolite but have no idea if it's from a mammal, dino or something else. Any shared wisdom would be greatly appreciated. Thanks :-D

Hello! If anyone could help me out with this it would be appreciated. This opal replacement fossil was mined in New South Wales, about 6 years ago. I found it in a parcel of Lightning Ridge rough and have been trying to identify it for a while now. The closest I have come to a positive match (Still not a match but it's close) is the Molar of a giant Marsupial from the order Diprotodontia. There is a wee problem with this, I've read Lightning Ridge Opal is supposed to be from the Cretaceous and Jurassic periods, a minimum of 66 million years old. The Diprotodontia existed throughout most of the Pleistocene, about 63 million years off. HELP! Thanks in advance everybody. :-)

Blue Petrified Wood Real?
Aceofspades posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, Is this real petrified wood? Never seen blue in wood before? I also haven’t seen any petrified wood faked. Seller seems legit and the information he/she provided about age and area check out. Any help appreciated. Travis

Hey everyone! I recently acquired this oyster from Tulear province, Madagascar. The seller has listed it as Rastellum carinatum, but doing any research online, I’ve only found other sellers selling similar fossils. I did come across a Wikipedia article for Agerostrea sp. It appears to be the same shell, and it lists it as occurring in rocks that are Maastrichtian age from Madagascar. Are these the same species just under different names or are they separate? If so, what genus does my specimen belong too? Any response would be greatly appreciated from you guys, we’ll see how challenging this might be to figure out. Thanks again -Nick
