AI-assisted summary
Description from the seller
科学名: †Thalassotitan atrox (Longrich ほか, 2022) 旧称 Prognathodon - モササウルの歯 - 2本セット。最大の known モササウル種
ロケーション: オウエッド・ゼム, モロッコ
地質形成: Ouled Abdoun盆地（リン鉱床）
時代: 上部白亜紀、マーストリヒタン層期、(~6600万年前)
サイズ: 12,9 cm（最大）
参考: #S609
DESCRIPTION:
観察: この巨大な Thalassotitan atrox は、最大級のモササウル種の一つである（旧称 Prognathodon sp）。歯は非常に保存状態が良い。エナメル質の質は非常に高く、カラメルの美しい色調が広がっている。
これらの歯は完全な根が付いている。しかし発掘時に歯冠が折れて根元から分離した。そのため標本は後に歯を接着・充填して冠を根に再接着する形で修復された。それ以外に修復は施されていない。
もう一つの非常に興味深い点は、根の中に新生代の置換歯孔（ germ-emerging replacement tooth hole）が確認できることである。モササウルは、サメや陸生恐竜のように生涯を通じて歯を絶えず置換する。歯が摩耗を始めると、その下で新しい歯が成長を始め、古い歯を置換する。ここには見事な例がある。
診断: 大型モササウル科、上顎前方の先端は短く鈍い。前上顎骨と上顎骨の間に噛み合う接触。上顎骨は深く、腹側縁は凸状。前頭骨と前方頭骨の間には一連の舌と溝状ジョイントによる結合があり、結合部の縁が互いに噛み合っている。前頭骨は前頭部を広く覆う。前頭-後眼窩前頭部が前方を除外する構造。前頭は短く幅広く、前方で強く細縮し、頭頂骨接触部で強く凹む。後眼窩突起は前方に移動、頭頂孔を包む大きな後内側突起。頬骨は上顎骨との接触部で幅広く頑丈。顎骨は巨大で、軸の中央値下部に大型の結合した上顎・下顎突起を持つ。歯冠は先端の紋様と前方・後方鋸状歯列の交互装飾を有する。
この種はモロッコ産リン鉱の中で最も一般的な種である。
すべての化石には真正証明書（Certificate of Authenticity）が付属する。毎週、発行される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る。証明書がまだ更新されていない場合はご連絡ください。すぐに更新します。展示箱は同梱されません。
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.
