Description from the seller

科学名: cf Ornithocheirid Pterosaur (cf Ornithocheirus simus, (Owen, 1861) - Pterosaur爪)

場所: Gadoufaoua, Téneré Desert, Niger.

地質成層: Erlhaz Formation

年代: 下部古生代前期(白亜紀前期、阿普坦/アルビアン期)(約1億1300万年)

サイズ: 1.9 cm

REF.: #J651

DESCRIPTION:
Ornithocheirus simus は断片的な顎先のみにしか知られていない。 その鼻先には、類縁種と類似した特徴的な凸形の“くさび”状の crest があった。 Ornithocheirus は、関連する Coloborhynchus や Tropeognathus に比べて顎先が比較的細く、これらは歯のロゼットが顕著に展開していたほか、Ornithocheirus 自体よりも発達した“くさび状”の crest を持っていた。もう一つの特徴として、Ornithocheirus の歯はほとんど挺出しておらず、外向きの角度で配置されていることが少なかった点が挙げられる。

過去には Ornithocheirus が現存した最大級の翼竜の一つで、翼幅はおよそ40フィート(12.2 m)に達したとされていた。

翼竜の爪の診断的特徴:

- 対称的な脈溝
- 指の爪の底が平ら
- 先端の曲がり角は翼竜の爪の特性の一つ: 先端の腹側端に薄い薄板状の骨 フランジまたはリッジが見られる。 急斜面で止まる際の掴みを最適化する適応と見なされ、岸壁に引っ掛ける際に役立つ。

この標本についての観察:

非常に珍しい上位クラスの標本で、ほぼ完整な状態に近い。 この爪を Ornithocheiridae 科に分類する。単一の爪だけでは正確な分類が困難であるが、少なくともこの爪は、ニジェールの初期白亜紀に記載されたこの科の翼竜に属すると考えられる。付随する骨片は接着され、復元はされていない。

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.

The Association of Applied Paleontological Sciences conforms to the recommendations of The National Academy of Sciences Report on Paleontological Collecting and standard business practices and ethics. In addition, we are the certified member #5681 of the International Meteorite Collectors Association (IMCA) and a certified member of GMA (Global Meteorite Association) G0043. IMCA and GMA are the most prestigious associations helping meteorite collectors in their search for Authentic Meteorites for their collections and assisting others in helping to learn more about meteorites. A physical certificate of authenticity is provided free of charge with every fossil we sell. This is our lifetime guarantee. The certificate, individually prepared for each fossil by Juan A. Poblador, an expert paleontologist, contains an accurate scientific description, and the certificate's validity can be verified online at all times. In addition, a 100% money-back guarantee is provided.
