AI-assisted summary

Description from the seller

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

場所: Fallon Co., Montana (私有地), USA

地質層: Hell Creek Fm

時代: 白亜紀末期、 Maastrichtian階段 (~68-66百万年前)

サイズ: 2,8cm

REF.: #J118

DESCRIPTION:

有名な白亜紀末のモンタナ州の堆積層からの正真正銘のNanotyrannus sp.歯。

この標本は明確な歯牙鋸状縁(carina)が非常に良好に保たれている。切断 edge(carina)に沿って非常に良好に保存された鋸齿を示す。復元や修理は一切なし。

100%自然のまま、全く修復なし。

Nanotyrannus lancensisは、白亜紀後期のHell Creek Formation出身の小型で速く機敏な tyrannosaurであり、元はLance Formationの一部だった、T. rexとは異なる小型さと顕著な違いで知られる。最近の研究は、それが別種であると確認しており、若年のT. rexではなく、特徴として歯の数が多い、手が大きい、独特の骨構造を持つなどの理由から、独立した種として位置づけられている。意味は「矮小な tyrant(小さな暴君)」であり、T. rexと共存する小型の捕食者だった。

主な事実

意味名: ギリシャ語の nanos(矮小)と tyrannos(暴君)から「矮小な暴君」。
種名: lancensisは頭骨が見つかったLance Formationを指す。
サイズ: 約15-18フィート、成体のT. rexよりかなり小型・軽量。
生息地: Hell Creek Formation(白亜紀後期)、T. rexと同じ時代・場所。
ライフスタイル: 速く機敏な追跡捕食者で、パキケファロサウルスなど小型恐竜を狙ったとされる。
論争: 長く独立した種か若年のT. rexかと議論されたが、最近の証拠はこれが独自の属であることを支持している。
識別特徴: T. rexよりも細長い頭蓋、より多くの歯、大きな手、異なる骨構造。

論争と結論
若年T. rex仮説: Hell Creekの小型ティラノサウルス化石の多くは若いT. rexと見なされていた。なぜなら大きなNanotyrannus化石が存在せず、T. rexの若年個体は珍しかったためである。
別種仮説: Nanotyrannusの化石には成熟した特徴(癒着した骨など)やT. rexが決して発達させなかった特徴が見られ、T. rexへ成長することが生物学的に不可能だと判明した。

現在の合意: Nanotyrannusは小型ティラノサウルスの別個の属であり、T. rexと共存する独自の機敏な捕食者として位置づけられている。

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.
