I had a good hunt at the North Sulphur River Texas. I found a nice variety and possibly the first Pterosaur limb bone ever found at NSR.

Pterosaur or Enantiornithine coracoids?
D.N.FossilmanLithuania posted a topic in General Fossil Discussion
Dear Guys, I have found three coracoid bones in flintstone that are about 0,5 cm length and made the cavities of them by needle. There are two versions about these fossil ID in my opinion- enantiornithine bird or pterosaur (pterosaur is more possible because the lower wider part of bones is not very wide as in almost all birds and the pterosaur, e.g. ornithocheiridae coracoid shape is very similar!). If these are pterosaur coracoid bones they should belong to small species (maybe rhamphorhynchoids), if small bird bones- they should be very primitive, probably early Cretaceous and I do not know any birds with this shape except Enantiophoenix (Enantiophoenix coracoid is even little wider and the bone cavity is very small, not so big as in my specimens). Please help to identify these remains by the coracoid form in pterosaurs, primitive birds or even tiny dinosaurs. Any help will be appreciated! Best Regards Domas- 3 replies

I've got this one fossil that I'm not quite sure how to classify it... It\s supposed to be a fossil Pterosaur tooth found in Kem Kem Beds of Morocco.... 1.75" long... However, it doesn't match any of my Pterosaur teeth... Or Crocodile, or Spinosaurus... Is it some sort of fish tooth? Thanks in advance, more pics if needed...

Hi, Saw this 'Pterosaur claw' for sale (first time i have seen something like this for sale) and would like to know if this is the correct id or if it is something else (i believe it might be fish but wanted to ask the experts). It is 1.3 inches long (3.3cm) and is from the Kem Kem. Thanks.

A few items I recently picked up at the Tucson show. Others will follow Nice size Pterosaur upper beak. Big Dorsal from a Theropod - needs to be prepped to remove matrix glued on the bone. Will tackle after the show. Spino Metatarsal Very Arthritic bone.. believe its Phalanx

Pterosaur tooth from Kem Kem, Morocco. -
From the album: MY FOSSIL Collection - Dpaul7
Pterosaur tooth Morocco Late Triassic–Late Cretaceous Pterosaurs (from the Greek "pterosauros", meaning "winged lizard") were flying reptiles of the extinct clade or order Pterosauria. They existed from the late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. Early species had long, fully toothed jaws and long tails, while later forms had a highly reduced tail, and some lacked teeth. Many sported furry coats made up of hair-like filaments known as pycnofibers, which covered their bodies and parts of their wings. Pterosaurs spanned a wide range of adult sizes, from the very small anurognathids to the largest known flying creatures of all time, including Quetzalcoatlus and Hatzegopteryx. Pterosaurs are often referred to in the popular media and by the general public as "flying dinosaurs", but this is scientifically incorrect. The term "dinosaur" is restricted to just those reptiles descended from the last common ancestor of the groups Saurischia and Ornithischia (clade Dinosauria, which includes birds), and current scientific consensus is that this group excludes the pterosaurs, as well as the various groups of extinct marine reptiles, such as ichthyosaurs, plesiosaurs, and mosasaurs. Like the dinosaurs, and unlike these other reptiles, pterosaurs are more closely related to birds than to crocodiles or any other living reptile. Pterosaurs are also colloquially referred to as pterodactyls, particularly in fiction and by journalists. Technically, "Pterodactyl" refers only to members of the genus Pterodactylus, and more broadly to members of the suborder Pterodactyloidea of the pterosaurs. The anatomy of pterosaurs was highly modified from their reptilian ancestors by the adaption to flight. Pterosaur bones were hollow and air-filled, like the bones of birds. They had a keeled breastbone that was developed for the attachment of flight muscles and an enlarged brain that shows specialised features associated with flight. In some later pterosaurs, the backbone over the shoulders fused into a structure known as a notarium, which served to stiffen the torso during flight, and provide a stable support for the scapula (shoulder blade). Most pterosaur skulls had elongated jaws with a full complement of needle-like teeth. In some cases, fossilized keratinous beak tissue has been preserved, though in toothed forms, the beak is small and restricted to the jaw tips and does not involve the teeth. Some advanced beaked forms were toothless, such as the pteranodonts and azhdarchids, and had larger, more extensive, and more bird-like beaks.
