Here is the find we made in SC. I think It is a fragment of a baby alligator or croc. Found it on the beach in the surf. Any thoughts? And how rare are these little guys?

I found this tiny tooth today looking through some matrix I had previously searched. I always search any matrix at least a second time after re-cleaning it. The matrix is from a Cretaceous river site here in North Carolina. The site is Black Creek Group, Bladen Formation. It is mainly marine, but many dinosaur teeth and bones are found there. My first thought was croc (Leidysuchus?), far posterior. But soemthing does not look right to me for it to be that. Looking for your thoughts. The tooth is 6.5 mm long, 4.9 mm wide and 4.1 mm tall. I apologize for the pics, my digital microscope is on the fritz. I edited these to try and get the best pictures I could.

Hi all... I finally got my new prep lab up and running and pulled a jacket out of storage. A pile of crocodilian scutes and a few bones form the Eocene Wasatch Fm of southwestern Wyoming. i have exposed the bones and I am stumped. Do I leave these bones in matrix to show them as found, or take them out and have a cool collection that is much more easily stored or displayed. They main argument for removing them is that it is a fairly big bloc, and I don't have all that much display space, and it is not really articualted. The main argument for displaying as is is that it would be a lot less work. A lot less. I kinda want to know what you folks think. I was hoping I would find a skull or a jaw, but no such luck yet, although there are few areas that puzzle me. Here are some pix. Notice that it is primarily scutes, as croc skeletons tend to be. and a few closer up shots. Here is a pile of scutes. and here are two leg bones... and a bunch more scutes, and at the top of the picture is a string of articulated verts. Here is another shot of the verts. Through the out-of-focusitude, notice how fractured they are. These will be a lot of fun to put back together, but they will look a lot better (I hope). Thanks for looking and What would you do?

When I was just looking at my croc coprolite specimens from the marine Paleocene Aquia Formation of Liverpool Point Maryland I noticed this interesting 3.75 inch by 2 inch specimen. I hadn’t noticed before that it contains furrows. See the second picture which I darkened a bit to try to better show the furrows. They are much more obvious when looking at the specimen itself. I learned about furrows from Lori’s post below. http://www.thefossilforum.com/index.php?/topic/78589-possible-amphibian-jawmaxillary-with-teeth-in-coprolite/&tab=comments#comment-829344 I’ve now seen furrows in several croc coprolite specimens from the Paleocene of Maryland and the Eocene of Virginia. Crocs have extremely strong stomach acid. So strong that I’ve read in several papers that captive crocs fed a diet of chickens and/or rodents have no bones in their coprolites. Interestingly their coprolites do show feather and hair traces. Anyone else have coprolites with furrows? Lori @GeschWhat I know you do. Please post some pictures.

Found this tooth today at Post Oak Creek. Don't think it is mosasaur. Doesn't look right. Thinking it could be plesiosaur or croc? I have one worn plesiosaur I found a couple of years ago. Thoughts?

Got this tooth in a trade package. The exact locality is unknown, but is somewhere west of the Mississippi. It seems similar to the gator and croc teeth I have found down here in Bone Valley Florida, but the interior structure appears different. Any ideas what this might be?

Our family of 3 attended the special event that was held at Stratford Hall yesterday. Dr. Weems was the guest speaker. This was our second year participating in the event. I liked it being in June instead of August this year. It was warm but not as hot as August. Tides were decent. Here is what the three of us managed to find. (Pretty good day) Can't wait for next year.

Hi all, I have acquired this skull from Sragen, Java. Can someone confirm or ID it as a crocodylus Porosus please. I also have no idea of value if people can give me an indication that would be great. Whether for sale or insurance value as I haven't decided yet. I've given it a good look over, no restoration at all, as it came out the ground. It is 880mm long and 450mm at its widest point.

Asking for some help if I could get an ID on the species of this recent find of mine? I've pulled from GMR (GreensMill Run Greenville NC) Rick noted it's def. Reptile but unsure 100% if it's Croc or mossasaur? Any clarification on that and if there is enough of it to go further into a species/placement/relative size of what it belonged to would be AMAZING! I found it with the usual GMR assembly of great white, tiger shark teeth, whale bone/ear bone, a mossasaur tooth and petrified wood.

Most of the material I have seen on Lee Creek crocodiles have identified them to the Genus Thecachampsa; and to the species antiqua. However, I have one tooth that is different from all the others. Are there others species of croc present in the Lee Creek fauna? This tooth is almost a dead wringer for the tooth pictured in this drawing by William Bullock Clark The tooth in this drawing id identified as Thecachampsa contusor (Cope, 1867) Illustration of a tooth of Thecachampsa contusor (=Thecachampsa antiqua) collected from Aquia Creek, Maryland. 4a. Lateral view. 4b. Basal view. Printed in Eocene, Volume 1 by the Maryland Geological Survey, William Bullock Clark (1901). So second, is T. antiqua synonymous with T. contusor. Here is the tooth

A nice Lee Creek croc tooth.

I got to hit Flag Ponds for a few hours this afternoon. It was blustery and 33°, but turned out to be a pretty good day. These are the best from today.

any help please.....I'm hoping its a worn partial croc or mosasaur tooth,but what do you guys think...

Hi: Me again. I found this at Aurora, NC Phosphate mine many moons ago. I am unsure if it's an alligator, mosasaur tooth or something else. Thanks for the help. David .

I joined in with a few others for a trip into an quarry in eastern N.C. This quarry is Oligocene Belgrade and River Bend Formations. It was a beautiful day for a hunt though part of the quarry was flooded from rains due to Hurricane Mathew and the rest of it was on the muddy side. The finds were not as prolific as I thought they would be after all of the rain, but still not a bad day. These are some of the better finds. All together ......... Croc teeth, the small one is 7/8 inch long and may be the best condition one I have ever found here. The larger is 1 1/16 a couple of Hemispristis 1/2 inch and 3/4 inch

Bizarre Fake Elasmosaur Skull
LordTrilobite posted a topic in Is It Real? How to Recognize Fossil Fabrications
I came across this absolutely bizarre looking skull on our favourite auction site. Most of the bones look pretty real. It looks nothing like the known Elasmosaur from Khouribda. Zarafasaura has a really short nose and gigantic jaw muscles. Besides the teeth this looks nothing like it. Most of the bone seems to be real and while there definitely seems to be some repair/construction. Most of the real bones seem to fit together. Some of the teeth are definitely plastered in. Though there seem to be some unerupted teeth that do actually belong to the jaws. The top of the snout also looks completely bizarre. What I think has happened here... Is that someone took a crocodile, mosasaur and elasmosaur and mashed them together. Look at the back of the skull. This looks like the back of a crocodile skull to me. I'm not sure where the jaws come from (maybe croc?) but the teeth are definitely those of a plesiosaur, probably Zarafasaura. The top of the snout had me confused for a few minutes but I think that this is actually the frontal and parietal of a mosasaur. Notice what looks like the parietal eye filled in with a chunk of bone in the middle top off the skull. So yeah I think this is an absolute abomination. Steer clear folks...- 9 replies

Hi, I found this croc tooth for sale and it's labeled as Sarcosuchus. If it is Sarcosuchus, I want to buy it. They didn't put very much info about it, just that it is from Africa. Any help?

Pedro L. Godoy, Felipe C. Montefeltro, Mark A. Norell & Max C. Langer (2014)An Additional Baurusuchid from the Cretaceous of Brazil with Evidenceof Interspecific Predation among Crocodyliformes.PLoS ONE 9(5): e97138.doi:10.1371/journal.pone.0097138 Free PDF paper http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0097138 Abstract A new Baurusuchidae (Crocodyliformes, Mesoeucrocodylia), Aplestosuchussordidus, is described based on a nearly complete skeleton collectedin deposits of the Adamantina Formation (Bauru Group, Late Cretaceous)of Brazil. The nesting of the new taxon within Baurusuchidae can beensured based on several exclusive skull features of this clade, suchas the quadrate depression, medial approximation of the prefrontals,rostral extension of palatines (not reaching the level of the rostralmargin of suborbital fenestrae), cylindrical dorsal portion ofpalatine bar, ridge on the ectopterygoid-jugal articulation, andsupraoccipital with restricted thin transversal exposure in thecaudalmost part of the skull roof. A newly proposed phylogeny ofBaurusuchidae encompasses A. sordidus and recently described forms,suggesting its sixter-taxon relationship to Baurusuchus albertoi,within Baurusuchinae. Additionally, the remains of a sphagesauridcrocodyliform were preserved in the abdominal cavity of the newbaurusuchid. Direct fossil evidence of behavioral interaction amongfossil crocodyliforms is rare and mostly restricted to bite marksresulting from predation, as well as possible conspecific male-to-maleaggression. This is the first time that a direct and unmistakenevidence of predation between different taxa of this group is recordedas fossils. This discovery confirms that baurusuchids were toppredators of their time, with sphagesaurids occupying a lower trophicposition, possibly with a more generalist diet.

My friend found this from the bottom of a river in Thailand and brought this to me to see if its a skull from recently dead croc or is it a fossil. My gut feeling tells me its a recently dead croc since it wasn't dug or excavated from a known fossil deposit but I can't be sure; I have heard of people getting fossils from the bottom of the river so it could be possible. Here are what it looks like: It could be a current specie like the Crocodylus Siamensis, but I guess I will let someone with more experienced with croc biology to be able to confirm that. So what are the things that u can do to test to tell for certain if its a bone or a fossil? Other than carbon-dating that is. Anyway thx for the help guys.
