AI-assisted summary
Description from the seller
学名: 未同定のベラソアリド類 - (原始鯨の祖先) - Potencial cf Pappocetus lugardi - 同一牙骨内に2つの臼歯がまだ関連付けられている
産地: ダフラ、サハラ西部、南モロッコ
地質構成: Samlat - Aridal Formation
年代: 測定上のエオシーン後期（約4000万年）
サイズ: 7.5 × 7.5 cm
REF.: #J580
説明:
Pappocetus lugardi の cf を含む臼歯の美麗な保存状態で、 protocetid 哺乳類（初期鯨の祖先）の一種です。臼歯はまだ歯骨の残骸内に位置しており、それに自然に付随しています。これらの優れた歯は、モロッコのガラン近郊の西サハラにある中期エオシーン世の Aridal および Samlat Formation に由来します。一般にはサメ Otodus sokolovi (Carcharocles auriculatus) の歯と共に見られ、メガロドンの祖先とされます。
歯冠の結合部に接着剤で補強されたひび割れがいくつか埋められており、歯骨には補填の点が散在していますが、重大な欠陥はありません。驚異的な標本です。これは臼歯の最終段の歯です。
Pappocetus lugardi は、エオシーン紀に Africa で生息していた protocetid 鯨の絶滅種です。陸と海の過渡形態として、約 20–25 フィート（約 6–7.5 m）のこの两生類の捕食者は Basilosaurus の祖先と考えられ、鯨類 evolution の重要な段階を示します。
Pappocetus lugardi の主な事実:
発見: 1920 年に C.W. Andrews がナイジェリアの Ameki Formation の化石に基づいて初めて記述。追加標本はモロッコのサハラ砂漠で見つかっています。
進化的位置: Pappocetus は Protocetidae 属で、初期の兩生類の鯨であり、巨大な四肢を使って陸上を移動できる一方、泳ぐ能力も有していたと考えられます。
形態特性:
サイズ: 約 20–25 フィート（約 6–7.5 m）
食性/習性: 大型の兩生類の陸海両用の捕食者で、頑丈な歯を有し、狩りには視覚と嗅覚を頼っていた可能性が高い。
外観: 先代より鯨類らしく、流線型の体を持つが、機能する後肢はある程度退化している。
化石記録: 顎の破片、歯、頭蓋骨材料から知られている。
現代の鯨類との関係: 過渡形であるものの、後の捕鯨類に見られる現代的なエコーロケーション機能を有していたとは考えにくい。
我々の化石にはすべて真贋証明書が付属します。毎週、真贋証明書は公式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。証明書が未更新の場合は、お問い合わせいただければ直ちに更新します。表示箱は付属しません。
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.
