Description from the seller

科学名: †Ursus spelaeus (Rosenmüller, 1794) - 洞窟クマ - 「上顎」臼歯(M2)

場所: ポーランドの洞窟

地質構成: 深い洞窟や洞窟内の沈殿物で見つかる

年代: 後期更新世、第四紀(約50,000年前)

サイズ: 4,4 × 2,1 cm

REF.: #S1058

DESCRIPTION:

観察: 有名で巨大な氷河時代の洞窟クマ(Ursus spelaeus)に属する、印象的な上顎臼歯(M2)です。完全に自然の状態で、修復や補修は行われていません。適切な保存を確保するために、無色透明のプロフェッショナルな安定化剤Paraloid B72のみが適用されています。洞窟内で見つかるこの種の歯は、何千年もの間非常に高湿度にさらされてきました。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亀裂を生じ、急速に劣化します。したがって、このプロフェッショナルな実験室レベルの古生物学的保護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、暗い青色がかった美しい色合いを示します。これは、鉄やマンガン酸化物を含む鉱物質の水が、長い年月を通じて堆積物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、鉱化します。時には、多くの色は酸化マンガン(ペリクロー価格の八角石)によるものです。

すべての化石には真正証明書が付属します。毎週、発行された真正証明書は私たちのウェブサイト上のデータベース認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ことに気づいた場合は、お問い合わせください。すぐに更新します。表示ボックスは含まれていません。

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. Jurassic Dreams a proud member of the Association of Applied Paleontological Sciences (AAPS) and abide by its Code of Ethics. The Association of Applied Paleontological Sciences conforms to the recommendations of The National Academy of Sciences Report on Paleontological Collecting and standard business practices and ethics. In addition, we are the certified member #5681 of the International Meteorite Collectors Association (IMCA) and a certified member of GMA (Global Meteorite Association) G0043. IMCA and GMA are the most prestigious associations helping meteorite collectors in their search for Authentic Meteorites for their collections and assisting others in helping to learn more about meteorites. A physical certificate of authenticity is provided free of charge with every fossil we sell. This is our lifetime guarantee. The certificate, individually prepared for each fossil by Juan A. Poblador, an expert paleontologist, contains an accurate scientific description, and the certificate's validity can be verified online at all times. In addition, a 100% money-back guarantee is provided.
