AI-assisted summary

Description from the seller

種: †Acheroraptor temertyorum (Evans 2013 ほか) - Dromaeosauridae科 - テロポド恐竜の歯

年代: 後期白亜紀、マーストリヒタン期(約6700万年前〜6800万年前)

場所: アメリカ合衆国・ワイオミング州。私有地。

地層: Lance Creek Formation

サイズ: 0,7 cm

Ref. S612

説明:
Acheroraptor は主に Hell Creek Formation で知られていますが、同時代の地質的に類似する Lance Formation からも歯を含む断片的遺物が見つかっています。これらの化石は後期マーストリヒタンの時代に属します(約6600万年前頃)。

Acheroraptor の歯を同定するのは難しい場合がありますが、歯冠の先端と基部に向かう方向で微妙な apexobasal ライド(ひだ状)を持つことや、前方と後方の辺縁の鋸歯の大きさが異なることがある点が手掛かりになることがあります。

Lance Formation における Acheroraptor 歯の主な特徴:

地質学的背景: Hell Creek Formation と Lance Formation の化石は同じ後期マーストリヒタン期に属し、類似の古生物群を含むことが多い。

年代: 化石は約66百万年前頃とされます。

識別: Acheroraptor の歯は小型の肉食恐竜の歯で、特定の特徴を有することがありますが、同形成内の他の小型の肉食恐竜の歯と区別するのは難しいことがあります。

診断的特徴:
- 鋸歯: 前方辺と後方辺の鋸歯の大きさが異なることがある。
- ひだ: クラウンには apexobasal のひだが走ることがある。

同定の難しさ: 歯が限られ、断片的なことが多いため、同定は難しい場合がある。ほかのドロメオサウリッド類や類似の歯を持つ恐竜が含まれている可能性もある。

すべての化石には真正証明書が付属します。毎週、発行済みの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。直ちに更新します。表示ボックス同梱。

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.

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.
