AI-assisted summary
Description from the seller
科学名：Triceratops horridus, Marsh 1889（角竜類の三つ角恐竜）- 歯
場所：ワイオミング州 Weston郡（アメリカ合衆国）。私有地。
地質地層：Lance Creek Formation
年代：後期白亜紀、馬斯特リヒ期（約6600万年前～6800万年前）
サイズ：1,4cm
REF.: #J613
DESCRIPTION:
優れた partially rooted tooth（根付き部が部分的に残る歯）で、エナメル質が良好に保存され、咀嚼痕がよく発達しています。
Lance Formation の Triceratops horridus は、ワイオミング州周辺の後期白亜紀の岩石から見つかった三つ角恐竜の象徴的な化石を指し、T. prorsus と比べて長い吻部と眉角を特徴とすることが多く、後の prorsus が出現する直前の、恐竜の進化系統の初期形態を示します。
これらの化石には歯・角・骨片が含まれ、Triceratops の進化を理解するうえで重要です。horridus は短い鼻角と前方に傾く眉角といった特徴を示し、祖先種と子孫種とで異なります。
主要情報:
Triceratops horridus：Triceratops の二つの認定種の一つで、特徴的な「三つ角の顔」、草食性、そして防御またはDisplay（展示）用としての大きなフリルで知られています。
Lance Formation（L Fm.）：アメリカ西部にある地質単位（ワイオミング州、モンタナ州、ダコタ州）で、豊富な後期白亜紀の化石が産出され、Triceratops 標本も多く含まれ、約6600万年前を年代とします。
物理的特徴：horridus は一般に吻部がより長く、眉角が前方へ向かいやや外側へ開くのが特徴で、face が短く眉角が直立している prorsus とは区別されます。
進化：horridus は祖先種とみなされ、非鳥類恐竜が絶滅する直前に anagenesis（直線的進化）で prorsus へと進化したとされます。
意義:
Lance Fm. の化石は Triceratops の外見、行動（例：摂食、社会行動）、および最終的な進化段階を理解するうえで重要な証拠を提供します。
要するに「Triceratops horridus Lance Fm」は、恐竜時代の終焉直前の地層から見つかった古典的 Triceratops の化石を指し、属の系統における重要な種を表します。
すべての化石には真正性証明書が付属します。毎週、発行された真正性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。すぐに更新いたします。展示ボックス付。
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.
