AI-assisted summary
Description from the seller
Scientific name: †Ursus spelaeus (Rosenmüller, 1794) - Cave Bear - Lower Dentary Molar Tooth (M1)
Location: Polandの洞窟に所在する洞窟
Geological Formation: 深い洞窟や空洞の沉積物中で発見
Age: 後期更新世、第四紀紀（約50,000年前）
Size: 2,7 × 1,2 cm
REF.: #S1055
DESCRIPTION:
Ice Ageの有名で巨大な洞窟クマ（Ursus spelaeus）に属する、根元が特徴的な下顎第一臼歯（M1）です。完全な自然産物で、修復は一切行われていません。割れ目は接着された形跡はあるものの修復はされていないように見えます。適切な保存を確保するため、無色の専門的安定化剤Paraloid B72が施されています。洞窟内で見つかるこの種の歯は、何千年もの間非常に湿度が高い環境にさらされてきました。洞窟から掘り出される際には、内部の水分が蒸発し急速に脱水して、化石が割れやすく劣化が進みます。そのため、プロフェッショナルな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、深い色合いの美しい暗色系や青系、非常に多様な色を示します。これは、鉄とマンガン酸化物を含む鉱化水が沈殿物の中を循環し、長い年月をかけて化石化したためです。これらの酸化物は骨や歯の内部にも浸透し、鉱化を促します。しばしば色の大半は酸化マンガン（pyrolusite）によるものです。
私たちの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。証明書がまだ更新されていない場合は、お知らせいただければすぐに更新します。ディ스プレイボックスを同梱。
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.
