AI-assisted summary
Description from the seller
学名：†Ursus spelaeus (Rosenmüller, 1794) - ケーブベア - 下顎体の第一奥歯（M1）
場所：ポーランドの洞窟に位置する洞窟
地質形成：深い洞窟または洞窟の沈殿物の中で発見
年代：後期更新世、第四紀（約50,000年）
サイズ：32.3×27.3 mm
REF.：#S341
DESCRIPTION:
有名で巨大な氷河時代の洞窟ベア（Ursus spelaeus）に属する、非常に根の深い下顎第一臼歯（M1）です。完全に自然な状態で、補修・修復は一切行われていません。適切な保存を確保するため、無色の専門安定材Paraloid B72のみが適用されています。洞窟内で発見されるこの種の歯は、何千年もの間、極めて高い湿度にさらされています。洞窟から発掘されると、その構造内の水分が蒸発し、急速に脱水して亀裂が入り、化石の劣化が急速に進行します。このため、専門的なラボの古生物保護処置を適用することが重要です。
洞窟内で化石化した歯や骨は、通常、暗色系の美しい青みがかった色調や多彩な色合いを示します。これは、鉄やマンガン酸化物を含む無機化水が長年にわたり沈殿物中を循環し、化石化した歯や骨の構造にも鉱化が進むためです。これらの酸化物は、骨や歯の内部にも浸透して鉱物化を促します。しばしば、こうした色の大半はパイロル石（マンガン酸化物）によるものです。
すべての化石には真正証明書（Certificate of Authenticity）が付属します。毎週、発行された真正証明書は、ウェブサイトのデータベース検証システムで更新されます。もし証明書がまだ更新されていない場合は、お問い合わせください。直ちに更新します。展示ボックス付き。

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.
