REF.: #J627

DESCRIPTION:

標本に関する観察: しっかりと根付いた歯。修復・接着はなし。食餌痕がよく発達した真の宝石級標本。

Narindasaurus (特に Narindasaurus thevenini) は、マダガスカル中部ジュラ紀に属する Turiasauria 脊柱竜 dinosauр の属である。その歯は Turiasauria の特徴を示す。

Narindasaurus 歯の主要な特徴:

ハート形: クラウンは独特のハート型形態をしており、 Turiasaur の診断特徴の一つである。
非対称: 歯は非対称で、しばしば舌側へカーブを描く。
D字型断面: 歯は非対称の「D」字形で、唇側(外側)表面は凸で、舌側(内側)表面は平らか、あるいはわずかに凹んでいる。
表面質感: エナメル質表面は粗いと表現されることが多い。
サイズと形: 通常はスパチュレート状(スプーン型)で頑丈、植物食に適応。鋸歯はかなり発達している。
形状は Archaeodontosaurus に比較的似ているが、 Turiasaurid 歯の特徴的な非対称性を有している。

Narindasaurus は Turiasauria 群の中で最も古い known な member の一つで、マダガスカルの Isalo III Formation の中部ジュラ紀で化石が発見されている。

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.
