AI-assisted summary

Description from the seller

科学名: Tyrannosaur Dinosaur - Nanotyrannus sp - Theropod Dinosaur Tooth

場所: Fallon Co., モンタナ州(私有地), アメリカ合衆国

地質層: Hell Creek Fm

年代: 後期白亜紀、 Maastrichtian期(約68-66百万年前)

サイズ: 2,45cm

REF.: #J115

DESCRIPTION:

著名な後期白亜紀モンタナ州の堆積物から出土したNanotyrannus sp.の本物の歯。

この標本は自然な根の一部さえも保存しており、切歯の edge(カリナ)に沿って非常に良好に保存された鋭歯を示す。

100%天然で、修復・補修は一切なし。

Nanotyrannus lancensisは、後期白亜紀 Hell Creek Formation(元々は Lance Formation の一部)に属する小型で素早く機敏なティラノサウルス類で、T. rexと著しく異なる小型さが特徴とされ、最近の研究では若いT. rex ではなく別種であることが確認されている。特有の特徴として歯の多さ、より大きな手、異なる骨格構造などが挙げられる。意味は「矮小な暴君」で、T. rexと共存する小型の獲物を狙う有力な捕食者であったとされる。

主要事実

名称の意味: 「矮小な暴君」— ギリシャ語の nanos(小さな)と tyrannos(暴君)に由来。
種名: lancensis は頭骨が発見された Lance Formation に由来。
サイズ: 約15-18フィート(約4.5-5.5m)と、成体のT. rexよりはるかに小さく軽量。
生息地: Hell Creek Formation(後期白亜紀)、T. rexと同時期・同地。
ライフスタイル: 速く機敏な追跡型捕食者で、おそらくパキケファロサウルス類のような小型恐竜を狙っていた。
論争: 長年、別種か juvenile T. rex かで議論されてきたが、近年の証拠はそれが独自の属であることを強く支持。
識別特徴: T. rex より細い頭蓋骨、多数の歯、より大きな手、異なる骨格構造。

論争と結論

少年期T. rex説: ヘル・クリークの小型ティラノサウルスの化石は、T. rexの若年個体とみなされることが多かった。大きな Nanotyrannus 化石が存在しなかったことと、T. rexの若年個体が希少であったことが理由。

別種説: Nanotyrannus化石には成人に近い特徴(癒着した骨など)や、T. rexが一度も発達させなかった独自の特徴が見られ、成長してT. rexになることは生物学的に不可能と考えられる。

現在の結論: NanotyrannusはT. rexと共存する小型ティラノサウルスの別の独立した属である、というのが現在の見解。

すべての化石には真正証明書(Certificate of Authenticity)が付属します。毎週、真正証明書はウェブサイトのデータベース検証システム上で更新されます。もし証明書の更新がまだである場合は、お問い合わせください。すぐに更新します。展示箱付き。)

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.

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.
