AI-assisted summary
Description from the seller
Scientific name: †Jeholotriton paradoxus (Wang, 2000) - Primitive salamander - showing well-preserved, soft-tissue impressions.
Location: East Asia, Daohugou village of Inner Mongolia, China.
Geological Formation: Daohugou Beds - Tiaojishan Formation
Age: Middle-Late Jurassic ( 164 million years)
Size: 9cm the salamander body - Matrix: 12,9 x 6,5 x 0,5cm
REF.: #J158
DESCRIPTION:
Jeholotriton is a genus of primitive, neotenic (retaining larval features) salamanders from the Middle/Late Jurassic (approx. 164–155 Ma) of Inner Mongolia, China. Found in the Daohugou Beds, it is a key fossil for early urodele evolution, with specimens often showing well-preserved, soft-tissue impressions, short limbs, and 16-17 presacral vertebrae.
Key Details of Jeholotriton paradoxus:
Age and Location: Primarily found in the Daohugou Bed, which is considered late Middle Jurassic to early Late Jurassic, not the Early Cretaceous as previously thought.
Characteristics: It is a small salamander with a distinctively shaped "paradoxical" skull, from which it derives its species name, J. paradoxus. It shows paedomorphic features (retaining juvenile traits into adulthood), such as larval-like skull structure and unossified carpal/tarsal elements.
Diet: Studies of fossilized guts show that Jeholotriton (along with Chunerpeton) fed on aquatic, invertebrate prey such as juvenile conchostracans (Euestheria luanpingensis), indicating a specialized, lacustrine (lake-dwelling) diet.
Evolutionary Significance: Jeholotriton is considered a member of the Cryptobranchidae family (giant salamanders) and represents a key, early branch in the evolution of modern salamanders (Urodela).
Jeholotriton is often associated with the Jehol Biota, although the Daohugou fossils are actually older than the main Jehol fauna.
Observations about our specimen: Our specimen, among all others, we can consider it a masterpiece. Its extraordinarily well preserved.
Regarding to its preservation: It is exceptional as it corresponds to a "Konservat-Lagerstätten" fossil. Coined by Adolf Seilacher in 1970, Lagerstätte means "storage place" or "site". Konservat implies high-quality preservation. Focus on quality (exceptional preservation of soft parts).
Our specimen perfectly shows the impression of all soft parts.
During the excavation of the fossil, the final slab broke into various fragments which were subsequently glued and filled, making the piece stable again. Considering these restorations in the matrix, the fossil in itself does not pose any type of restoration other than the fractures that cross it and were glued and filled.
All of our fossils come with a Certificate of Authenticity. Every week, the issued Certificates of Authenticity are updated in our database verification system on our website. If you find that your certificate has not yet been updated, please contact us and we will update it immediately. Display box not included.
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.
