AI-assisted summary

Description from the seller

科学名: Oviraptor cf philoceratops, Osborn 1924。化石化した卵。Macroolithus yaotunensis(Elongatoolithidae)形

場所: ゴビ砂漠、東アジア

地質層: ジャドクタ Formation

年代: 白亜紀後期、カンパニアン期、およそ75百万年前

サイズ: 20 × 8.5 × 5 cm

REF.: #J494

DESCRIPTION:

白亜紀後期のジャドクタタ Formation(東アジアのゴビ砂漠)のオビラプター卵は、細長く、リッジ模様があり、元々はプロトケラトプスの餌として盗卵と誤認されていた。しかし胚の発見(例: IGM 100/971)により、それらがオビラプターに属することが確認された。

これらの卵は、しばしば円形の巣の中で対になって配置され、鳥類のような巣作り行動を示す theropod の証拠となっている。

ジャドクタタのオビラプター卵の要点:

初期認識の誤り: 1923年にロイ・チャップマン・アンドリュースによって発見され、プロトケラトプスの盗卵と考えられ、「卵泥棒」という名がついた。

巣作りの証拠: 1993年に記述された化石など、成体が卵を盗んでいたのではなく、むしろ自分の巣の上で巣を温めていた(巣をつついていた)ことを示している。

卵の特徴: 卵はMacroolithus yaotunensis(Elongatoolithidae)の形をとる。長い軸に沿うリッジを持つ長形の形状(長さ約163–198 mm)が特徴。

胚の発見: 代表的な標本としてIGM 100/971(最初の既知の肉鞭類胚)やウカ・トルゴドなどの現場の標本があり、卵と親の結びつきを確固たるものにした。

巣作り構造: 卵は対をなして配置され、円形で開かれた、あるいは部分的に覆われた巣を形成し、15個以上の卵が並ぶことが多い。

着色: オビラプトリド類の標本に関する研究は、これらの卵が色素を有しており、現代の鳥類の一部と似た青緑色の色合いを与える可能性があることを示唆している。

これらの発見は、恐竜と現代の鳥類の関係性の理解を橋渡しする上で重要であった。

本標本についての観察: 本品は完全に自然な状態で、未修復・未補修。表面の大部分は健全で、一部の領域のみが殻を失っている。サイズはこの種の平均と比べて非常に大きい。真の投資級の驚異。

すべての化石には真正証明書(Certificate of Authenticity)が付属します。毎週、発行された真正証明書は私たちのウェブサイト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、こちらまでご連絡ください。直ちに更新します。表示箱は付属しません。

Seller's Story

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.
