Since I live so close to the famous Morrison Formation I thought I would start doing some research on what it's like to fossil collect in it because I'm seriously considering finding a way to gain access to some private land and do a little bit of collecting. I have heard it said once that the rock of the Morrison is hard and requires special tools to dig in, and that consequently it's impossible to prospect for fossils in the Morrison the same way you would in, say, the Hell Creek Formation. How true is this? Is the only way to fossil collect in the Morrison to be in a quarry? My plan for gaining access to land to collect on is to simply ask landowners if I may fossil collect their in the same way that a hunter might ask a land owner if they can hunt on someone's land. I understand that the more committed of us fossil collectors will do this to gain access to collecting sites, but is there any reason why I should avoid this approach regarding collecting on the Morrison? Thanks for any information anyone has.

Stegosaurus tooth and unknown sauropod teeth from Morrison and Cloverly Formation
-Andy- posted a topic in Fossil ID
Hi all, I have 3 teeth here I need help with The first is a Stegosaurus tooth: It comes from Wyoming, USA. Morrison Formation. It looks like a Stego tooth to me in terms of size and morphology, based off this thread > --- Next, a supposed Barosaurus tooth: It comes from Sundance, Wyoming. Morrison Formation. I cannot find any good literature on Barosaurus teeth. This tooth doesn't seem to have the spade-like shape I usually associate with Camarasaurus teeth. --- Lastly, there is a sauropod tooth from the Cloverly Formation: It comes from Montana, USA. Cloverly Formation. I presume it is a Titanosauriform indet. based off these two papers: https://www.researchgate.net/publication/254315252_The_Beginning_of_the_Sauropod_Dinosaur_Hiatus_in_North_America_Insights_from_the_Lower_Cretaceous_Cloverly_Formation_of_Wyoming https://www.researchgate.net/publication/236886285_Vertebrate_Paleontology_of_the_Cloverly_Formation_Lower_Cretaceous_I_Faunal_Composition_Biogeographic_Relationships_and_Sampling Can I have your thoughts on these 3 teeth? Thank you. - Andy

Hello lately i have this sauropod tooth from morrison formation, size is 15/32″ what sauropod would it be form?
-
I acquired this tooth some years ago, and it was labeled as a stegosaurus tooth. However, I am having some difficulties distinguishing if it indeed comes from a stegosaurus or perhaps an ankylosaur or nodosaur. It comes from the Morrison Formation of Wyoming. Each tick mark on the last pic is a mm. What do you all think? Thanks!

I took these photos of a replica of the Allosaurus jimmadseni specimen "Big Al 2" at the Lewis Science Center in Orange Coast College earlier this year. Like the referred A. jimmadseni specimen "Big Al", it was excavated at Howe Quarry in Wyoming in the 1990s.

My family owned private land near garden park in Canon City, Colorado. This is a couple of pieces that were found there. I'm just curious on what body part they may be.

An interesting article that discusses the “Golden Age” of sauropods, the Morrison Formation is reported to have yielded 13 genera and 24 species of sauropods. For collectors makes identification of teeth a pretty daunting task... Paper. https://giw.utahgeology.org/giw/index.php/GIW/article/view/42

Hi, I saw this tooth for sale and i am wondering if it looks like it could be a Ceratosaurus tooth. I read something about Ceratosaurus teeth having vertical ridges on the inner crown so i think it could possibly be a good match. It is .75 inches long and comes from the Morrison Formation in Wyoming. Thanks.

Are these Morrison Formation bones possibly sauropod metatarsals? Have made 3d Models to help ID
DJandLIMON111 posted a topic in Fossil ID
I have researched for a while now on these bones i have in my collection and only thing i can find that is pretty close to what i have are sauropod metatarsals. Can anybody maybe confirm this or what they may be from? The 3D models are very accurate i put the measurements on the 3d models just click on the annotations. They are from the morrison formation here in Colorado, thanks to anybody that can help! 1st bone: 2nd bone: -

dinosaur man posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi I found this and was wondering if the ID was right. Just trying to improve my knowledge on fossils. It doesn’t look Theropod in origin, considering it doesn’t have the honeycomb texture of a Theropod fossil, Thank you!!

A very long time coming, over a decade in discussion, Allosaurus jimmadseni has finally been described in the attached OPEN paper The abstract says it best "Allosaurus is one of the best known theropod dinosaurs from the Jurassic and a crucial taxon in phylogenetic analyses. On the basis of an in-depth, firsthand study of the bulk of Allosaurus specimens housed in North American institutions, we describe here a new theropod dinosaur from the Upper Jurassic Morrison Formation of Western North America, Allosaurus jimmadseni sp. nov., based upon a remarkably complete articulated skeleton and skull and a second specimen with an articulated skull and associated skeleton. " https://peerj.com/articles/7803/ National Park Service article https://www.nps.gov/dino/learn/nature/allosaurus-jimmadseni.htm Article https://phys.org/news/2020-01-species-allosaurus-utah.html Collectors For those of us that collect teeth I'm sure that these teeth are indistinguishable from other Allosaurus species like Allosaurus fragilis and all teeth should all be identified as Allosaurus sp. including bones. Also please do not get taken by sellers claiming to offer Allosaurus jimmadseni teeth. Unless one comes off an identifiable skull its bogus.

So this tooth i have was labeled by the seller as an Allosaurus premax tooth. The tooth is still in the matrix and the tip of it has broken off. The tooth measures 15/16 " long and is from the morrison formation ( bone cabin quarry ) in wyoming.

These finds were reported a while back and this paper describes the finds. These two partial skeletons from Montana represent the northernmost occurrences of Stegosauria within North America ever recovered from the Morrison Formation http://app.pan.pl/article/item/app005852018.html

We have been working primarily on our shark program material but we did add a few new dinosaur fossils. For the most part they are pretty small in size but add quite a bit to the education we do. These represent some iconic and scientifically important dinosaurs. In addition to these small fossils, we added a 6" Trike frill piece from HC, a smaller piece of a Horseshoe Canyon Ceratopsian frill, and a 2.5" Hadro vert from that formation. These are excellent touch fossils so I am happy ! The small fossils are..... Dromaeosaurus sp. Judith River. I big thank you thank you to @Troodon for some ID help. This is a really nice tooth and I am really excited about this one. We can get into some fun science about the study of tooth wear in determining what dinosaurs ate.

Many of us collect material from the Morrison Formation especially teeth and claws. Not much is published to help us identify these items but this new paper gives us some insight into a new Troodontid that includes teeth and claws, Hesperornithoides miessleri https://peerj.com/articles/7247/ The serrations on the mesial carinae of maxillary teeth are smaller than the distal serrations as in basal dromaeosaurids. Mesial serrations are restricted to the apical third of the crown and appear absent in some teeth. Serrations are small (5.5 per mm distally)
