AI-assisted summary
Description from the seller
学名：†Ursus spelaeus (Rosenmüller, 1794) - 冰河期の洞窟クマ - 「上顎」 上顎臼歯（M2）
場所：ポーランドにある洞窟
地質形成：深い洞窟や洞窟内の沈殿物で見つかった
年代：後期更新世、第四紀紀（約5万年前）
サイズ：4.3 × 2.1 cm
REF.: #S1004
DESCRIPTION:
Observations: 著名で巨大なIce Ageの洞窟クマ（Ursus spelaeus）に属する、印象的な「上顎」の上顎臼歯（M2）。完全に自然な状態で、修復や修繕は一切なし。適切な保存を確保するために、無色の専門的安定化剤であるParaloid B72のみが適用されている。
洞窟内で見つかったこの種の歯は、数千年にわたり非常に高い湿度にさらされてきた。洞窟から掘り出されると、構造内部の水分が蒸発を始め、急速に脱水して化石が割れやすく、急速に劣化していく。そのため、この専門的な実験室レベルの保護を適用することが重要である。
洞窟内で化石化した歯や骨は、通常、美しく濃い色調の青黒い色や多様な色相を示す。これは、鉄分・マンガン酸化物を含んだミネラル化水が長年にわたって沈殿物中を循環した結果であり、これらの酸化物が骨や歯の構造にも浸透して鉱物化させるためである。ときには、これらの色の大半は菱鉄鉱（マンガン酸化物）によるものである。
当社のすべての化石には genuineness（真正性）証明書が付属している。毎週、発行された真正性証明書は当社ウェブサイトのデータベース検証システムで更新される。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。すぐに更新します。Display box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.
