AI-assisted summary

Description from the seller

科学名: cf Ornithocheirid Pterosaur(cf Ornithocheirus simus、Owen, 1861)- 翼竜の鉤爪

場所: ガドゥファウア、テネル砂漠、ニジェール。

地質層: Erlhaz層

年代: 初代白亜紀、阿普坦期/アルビアン期(約1億1300万年)

サイズ: 1.67 cm

REF.: #J1017

DESCRIPTION:
Ornithocheirus simus は、断片的な顎先からのみ知られている。鼻先には、親族に似た特徴的な凸状の稜冠を有していた。Ornithocheirus は、関連種の Coloborhynchus や Tropeognathus に比べて顎先が比較的細く、歯のロゼットが目立って拡張しており、Ornithocheirus より発達した“くさび状の”クレストを有していた。もう1つの特徴は、歯がほとんど垂直で、外向きの角度に設定されているのではなく、直立していた点である。

過去には Ornithocheirus が存在した最大級の翼竜の1つで、翼幅が約40フィート(12.2メートル)に達したと信じられていた。

鉤爪の診断的特徴:

-対称的な脈溝
-指の鉤の底部は平らである。
-先端の末端の屈曲は翼竜の鉤爪の特性の1つである。先端は腹側縁の先端に薄いフランジまたは骨の隆起を示す。急斜面にとまる際の最適なグリップの適応と考えられ、このフランジは崖に引っかかるのを助ける。

この標本についての観察:

珍しい上部の希少標本です。この鉤爪を Ornithocheiridae 科に分類しますが、鉤爪が1つしかないため正確な分類は非常に難しいです。しかし、これはニジェールの初期白亜紀のこの科の翼竜に属するはずです。復元・接着はしていません。

すべての化石には真偽証明書が付属します。毎週、発行された真偽証明書はウェブサイト上のデータベース検証システムで更新されます。証明書がまだ更新されていない場合はご連絡ください。すぐに更新します。表示箱を同梱しています。

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. Jurassic Dreams a proud member of the Association of Applied Paleontological Sciences (AAPS) and abide by its Code of Ethics. 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.
