AI-assisted summary
Description from the seller
Scientific name: cf Ornithocheirid Pterosaur ( cf Ornithocheirus simus, (Owen, 1861) - Pterosaur claw
Location: Gadoufaoua, Téneré Desert, Niger.
Geological Formation: Erlhaz Fm
Age: Lower Cretaceous, Aptian/Albian stage ( 113 million years)
Size: 1,9 cm
REF.: #J651
DESCRIPTION:
Ornithocheirus simus, is only known from fragmentary jaw tips. It bore a distinctive convex "keeled" crest on its snout similar to its relatives. Ornithocheirus had relatively narrow jaw tips compared to the related Coloborhynchus and Tropeognathus, which had prominently-expanded rosettes of teeth, as well as a more developed "keeled" crest compared to Ornithocheirus. Another feature that made Ornithocheirus unique and unlike its relatives, was that its teeth of were mostly vertical, rather than set at an outward-pointing angle.
It was believed in the past that Ornithocheirus was one of the largest pterosaurs to have existed, with a wingspan possibly measuring 40 feet (12.2 m) wide.
Diagnostic characteristics of pterosaur claws:
-Symmetrical vein grooves
-The bottom of the digit claw is flat.
-The bend at the end of the tip is a specific trait of Pterosaur claws: The tip shows a thin flange or ridge of bone on the very tip on the ventral edge. It could be considered an adaptation for the best grip when perching on steep surfaces. That flange aids in hooking on cliffs.
Observations about this specimen:
Unsual top rare specimen, almost fully complete. We assign this claw to the family Ornithocheiridae, since a precise taxonomic classification is very difficult to arrive at with only one claw. However, it must belong to a pterosaur of this family, which has been described from the Early Cretaceous of Niger. It only has a glued but not restored fracture.
All of our fossils come with a Certificate of Authenticity. Every week, the issued Certificates of Authenticity are updated in our database verification system on our website. If you find that your certificate has not yet been updated, please contact us and we will update it immediately. Display box included.
Seller's Story
Jurassic Dreams is the world's largest online dinosaur fossils store, unrivaled as the most reputable source for authentic fossil specimens. We are the only leading online fossils store owned by an accredited geologist and paleontology expert. In addition, we have extraordinary authentic meteorites specimens from all over the universe.
With dozens of different specimens in stock... our customers come back time and again. Because, simply put, our lifetime guarantee is unbeatable.
My name is Juan A. Poblador and I have a strong academic background in Paleontology and Geology from the University of Madrid and University of Alicante. I have participated in fossil excavation projects in several locations mainly in Europe and Africa for over 10 years. Writing scientifically accurate descriptions of every specimen is one of the tasks that consume most of my time. Obviously, recognizing fake and restored fossils is second nature to me. So you can be sure that every fossil in this website has been carefully screened and inspected by me.
I have served collectors and fossil enthusiasts over the years. I have also supplied museums and institutions. I combine the study and research of significant specimens with exhibiting and selling the many other finds, which helps fund the new expeditions.
Additionally, I have a small team of support staff for logistics. I've personally trained them to handle and pack the fossils properly so that they can be shipped within 24 hours and arrive at your door in one piece.
Last but not least, I'm fortunate to have a great network of other seasoned paleontologists with whom I discuss the rarest items, new discoveries, and exploration trips to remote quarries... If I don't know something, the paleontological community really helps out.
I like to manage Jurassic Dreams as a well curated online exhibition of museum grade pieces. I'm a collector myself and I love to share the knowledge with other fellow collectors. That's why I will respond to any email when you have any doubt or when you buy, and you'll have a personalized fossil selection experience.
