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点セット。最大の known なモササウル類の種
場所：モロッコ、オウェド・ゼム
地質形成：オウレッド・アブドゥン盆地（リン鉱層）
年代：上部白亜紀、マースシアン期、約6600万年前
サイズ：13.1 cm（最大）
REF.: #S1017
DESCRIPTION:
観察：この巨大な Thalassotitan atrox は、既知のモササウル類の中でも最も大きい種の一つです（旧称 Prognathodon sp）。歯は非常に保存状態が良く、エナメル質の品質はキャラメルのような美しい色調のグラデーションのおかげで極めて高いです。
これらの歯は完全に根元が付いています。しかし発掘時にクラウンが破損し、根から分離しました。そのため、これらの標本は後に歯を接着・充填してクラウンを根に再固定する restoration が行われました。それ以外の修復はありません。
興味深い点として、根の内部に生じた未成熟の置換歯穴が見えることです。モササウルは、サメや陸上の恐竜のように生涯を通じて歯を絶えず置換します。歯が摩耗し始めると、下から新しい歯が成長してそれを置換します。これはその素晴らしい例です。
診断：大型モササウル類、前上顎骨先端は短く鈍い。前上顎骨と上顎骨の嵌合接触。上顎骨は深く、腹側縁は屈曲。前頭骨と上前頭骨の間に舌形・溝形の接合が連続しており、接合縁が互いに嵌合する。前頭骨は広く前頭骨に覆いかぶさる。前頭-眼窩前頭骨は前方の縁を部分的に除外。前頭骨は短く広く、前方に強く狭まり、頭頂葉に接する部で強く凹む。後眼窩突起は前方へ移動。蝶形突起は広く、頭頂孔を包み込む。
頬骨は上顎骨と接する部分が広く頑丈。方形骨は巨大で、シャフトの中央部以下には大きな結合した上方・下方の突起がある。歯冠には先端の網状装飾と前方・後方歯冠縁の鋸歯状縁がある。
この種はモロッコ産 phosphates（リン鉱）で最も普通に見られる種です。

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.
