Description from the seller
Scientific name: 未特定のベラソウリド類（Primitive whale ancestor）- cf Pappocetus lugardi の可能性 - 根付き犬歯
Location: ダクラー/西サハラ、南モロッコ
Geological Formation: Samlat - Aridal Formation
Age: 後期始新世（約4000万年前）
Size: 9,3 cm
REF.: #J692
DESCRIPTION:
cf Pappocetus lugardi の犬歯は、 protocetid cetacean（初期クジラの祖先）に属する vertebral toothの美しく保存された歯です。これらの卓越した歯は、モロッコのグエラン近郊の西サハラにある中期始新世のAridalおよびSamlat formations由来です。彼らはしばしばサメ Otodus sokolovi (Carcharocles auriculatus) の歯と関連して出現します。オットドゥス・ソコロビの祖先である巨大なサメと関連付けられることが多いです。
根の多くにはわずかな修復がありますが、根の基部が主に修復されています。その他の根とほぼ全体の歯冠はほぼ自然のままです。標本は長期保存のためParaloid B72で安定化されています。これは下顎犬歯です。
Pappocetus lugardiは、アフリカで約40–44百万年前に生存していた始新世の絶滅種の protocetid cetaceanです。陸と海の橋渡し形態として、この两栖性の20–25フィート長の肉食獣はベサロサウルスの祖先とみなされ、クジラの進化における重要な段階を表します。
Pappocetus lugardiについての主要事実:
発見: 1920年にC.W. Andrewsによって最初に記載。ナイジェリアのアメリキ層準の化石に基づく。サハラ砂漠のモロッコでも追加標本が見つかっている。
進化的地位: Protocetidae科に属する初期の两栖性クジラで、脚の大きな四肢を使って陸上を移動できた可能性があり、泳ぐ能力も備えていた。
物理的特徴:
サイズ: 全長約20–25フィート程度と推定。
食性/習性: 大型の两栖性水生肉食獣で、頑健な歯を持ち、狩猟には視覚と嗅覚に依存していたと考えられる。
外観: 初期のクジラよりもクジラらしい外観で、流線型の体をしているが、機能的な後肢は残っているものの退化している。
化石記録: 顎の破片、歯、頭蓋骨材料が知られている。
現代のクジラとの関係: 移行形であるが、後のクジラにみられる現代的なエコーロケーション能力を有していたとは考えにくい。
すべての化石には真正性証明書が付随します。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。すぐに更新します。表示ボックスは同梱されません。
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.
