Description from the seller

種: Dromaeosaur indet - family Dromaeosauridae - テロポド猛禽類の恐竜 前顎歯(PREMAXILLARY Tooth)

年代: 白亜紀後期、カンパニアン期(約7900万〜7500万年前)

場所: アメリカ合衆国・モンタナ州 私有牧場

地層: Judith River Formation

サイズ: 7.3 mm

Ref. S219

DESCRIPTION:
Judith River Formation の Dromaeosaur teeth は白亜紀後期に属し、羽毛を有する猛禽類のような恐竜、Dromaeosaurus や Saurornitholestes などに由来します。

これらの歯は通常小さく、鋭く、鋸歯状で、小型の爬虫類、哺乳類、幼体恐竜などを主食とする食性に適しています。識別の鍵となる特徴には、前方列の歯槽縁の独特なねじれと、前縁より後縁の方が鋸歯が細かいことが挙げられます。

Judith River Formation のドロマエオサウル歯の特徴

分類: これらの歯は、小型で高速な竜脚類として知られるドロマエオサウルス類、いわゆる「暴れん坊」恐竜に由来します。

時代: 白亜紀後期のカンパニアン期に属し、およそ79〜75百万年前のものです。

食性: これらの恐竜は小動物を捕食する捕食者であり、歯はその目的に適しています。

特徴:
鋸歯状の縁: 歯の縁には鋸歯が沿っており、小さな歯のような鋭い歯が並んでいます。
ねじれた歯槽縁: 重要な特徴として、前方縁の歯槽縁にねじれが見られます。
鋸歯密度: 前縁は後縁より鋸歯が細かい場合があり、前縁約22本/5mm、後縁約17本/5mm程度です。
複数種: 形成層には、より頑丈な Dromaeosaurus やより細身の Saurornitholestes など、異なるドロマエオサウルス種の歯が含まれています。

本標本についての観察: 形態は前鼻歯(premaxillary tooth)に対応します。真の希少品。最も厳密な細部を嗜むコレクター向けの tiny jewel のような逸品です。

歯は展示箱に収蔵されています。

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.

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.
