Paper by Phil Mannion et al. that supports the validity of the 24 recognized Sauropod species in the Morrison Formation. Some authors have suggested this number is well overestimated and represent growth series. https://royalsocietypublishing.org/doi/10.1098/rsos.210377

Camarasaurus Vertebra Restoration
Bguild posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi Everyone - I came across this Camarasaurus vertebra and was curious how much restoration has been done to it. I'm trying to train my eye for Morrison Formation material which can be a little tricky . Camarasaurus Tail Vertebrae Jurassic (145 Million – 155 Million Years Ago) Morrison Formation - Wyoming 4 1/4" long Thanks for taking a look! -
Quick guide to help identify a few Sauropod teeth from the Morrison Formation. Corrections and additional info always appreciated Please Note: Variations in the morphology of these teeth can vary significantly do to, species, jaw position and ontogenetic changes. This is just a high level guide. Camarasaurus: - Crown is wider than the root - Anterior Teeth are spoon-like and symmetrical, mid and posterior teeth are asymmetrical - The crown enamel ends sharply where the root begins - Wear facet, if present, can be on both sides of the tip

This is a rock shop purchase. The owner is an expert in dinosaur gembone from the Morrison. He also deals in Hermanophyton ferns, etc so he also knows a bit about paleobotany. But this piece was a mystery to him. Its very well agatized and the fine details are preserved. At first it looks like a limb cast. The exterior is coarsely wrinkled, like bark. The cross-section does not preserve a convincing ring of a bark layer, but there is some kind of concentric character. It has some characteristics of a limb bone. The geometry and size fit that t

Got a bit of a potential challenge here today! I recently bought this little toe bone (phalanx or metatarsal I guess) online. It was cheap, I guess because it doesn't have anything in terms of location/age other than Morrison Formation. It is about 6 cm long, 6-ish on its widest point and about 5 high at the highest point. It is quite heavy and stubby. Slightly distorted at the front and the circular parts at the front are partially worn off. Has a piece knocked out of it. Which is kind of neat because you can see the internal bone structure in that part. But the main question of c

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

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 toot- 3 replies

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.

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.
