Description from the seller
学名: 未同定バシロサウルス類(初期クジラの ancestors) - 潜在的には Pappocetus lugardi または Zygorhiza kochii 属種- 犬歯および前臼歯
場所: ダクラ、スペイン語圏西サハラ、モロッコ南部
地質層: Samlat - Aridal Formations
年齢: 晩期始新世（約40百万年）
サイズ(最大の前臼歯まで): 13,9 cm
REF.: #J581
DESCRIPTION:
Pappocetus lugardi または Zygorhiza kochii のタイプの protocetid cetacean(初期クジラの祖先)に属する、巨大な根付の犬歯と第一前臼歯。これらの卓越した歯は、中期始新世の Aridal および Samlat Formations に由来し、西サハラのモロッコ・ゲラン近郊に位置します。彼らはしばしばサメ Otodus sokolovi(Carcharocles auriculatus) の歯とともに見つかることが多く、メガロドンの祖先と考えられています。
修復/修理/コメントについての観察: 歯冠は非常に美しいのですが、割れ目があり、充填法を用いて修復された形跡があります。
根端は自然ですが、根の一部は修復・再成形され、元の形状へと復元するために修復材料と充填材が用いられています。
これらの修復にもかかわらず、彼らは真に雄大な巨大標本です。
Pappocetus lugardi は、約40–44百万年前のアフリカに生息していた始新世の絶滅した protocetid クジラの一種です。陸と海の移行形態として、これは水陸両用で全長20–25フィートの捕食動物であり、 Basilosaurus の祖先とみなされ、クジラの進化における重要な段階を表しています。
Pappocetus lugardi に関する主な事実:
発見: 1920年、C.W. Andrews によってナイジェリアの Ameki Formation の化石に基づき初めて記述。モロッコのサハラ砂漠でも追加標本が発見されている。
進化的位置: Protocetidae科に属し、陸上で大きな四肢を使って移動でき、同時に泳ぐ能力を持つ初期の amphibious クジラである。
外観: よりクジラに近い外観を持つが、前肢が完全には消失せず、流線形の体つきで、機能的だが縮小した後肢を保持している。
化石記録: 下顎片、歯、頭蓋材料で知られている。
現代のクジラとの関係: 移行形である一方、後の捕食動物に見られる現代的なエコロケーション機能を持っていた可能性は低い。
すべての化石には真偽証明書(Certificate of Authenticity) が付属します。毎週、真偽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。即座に更新いたします。

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.
