Description from the seller
Scientific name: †Ursus spelaeus (Rosenmüller, 1794) - Cave Bear - Lower Dentary Molar Tooth (M1)
Location: ポーランドにある洞窟
Geological Formation: 深部洞窟または洞窟の堆積物中で発見
Age: 後期更新世、第四紀期（約5万年前）
Size: 3.2 × 1.5 cm
REF.: #S1006
DESCRIPTION:
著名で巨大な氷河期の洞窟クマ（Ursus spelaeus）に属する、根元までしっかりと残る下顎第一臼歯（M1）です。完全に自然の状態で、修復や補修は一切ありません。適切な保存を確保するために、色のない専門的安定剤Paraloid B72のみが塗布されています。洞窟内で見つかるこの種の歯は、長い年月にわたり非常に高い湿度にさらされてきました。洞窟から掘り出されると、内部の水分が蒸発を始め、急速に脱水して化石が亀裂し、急速に劣化します。したがって、この専門的な研究室レベルの保護処置を施すことが重要です。
洞窟内で化石化する歯や骨は通常、美しい濃色系・青みがかった色調と多様な色を示します。これは、鉄やマンガン酸化物を含む鉱化水が、何千年にもわたって化石化した沈殿物の中を循環したためです。これらの酸化物は骨や歯の構造にも浸透して鉱化させます。時には、これらの色の大半は二酸化マンガン（マンガン酸化物）の影響です。
すべての化石には真贋証明書が付属します。毎週、発行された真贋証明書はウェブサイトのデータベース検証システム上で更新されます。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。表示ボックスを同梱します。
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.
