Description from the seller
Scientific name: Ouranosaurus nigeriensis, (Taquet, 1976) - 基底的 Hadrosauriform - Iguanodontian
Location: Gadoufaoua, Téneré Desert, Niger.
Geological Formation: Erlhaz Fm
Age: Lower Cretaceous, Aptian/Albian stage ( 113 million years)
Size: 2,3cm
REF.: #S578
DESCRIPTION:
Observations about our specimen: Truly huge adult with unusual size. Nicely developed feeding wear. No restorations or repairs. An authentic Ouranosaurus tooth masterpiece. Enamel color its aoustanding as well, showing deep black colors.
Ouranosaurus nigeriensis is a 7–8 meter (23–27 ft) long, herbivorous dinosaur that lived in Niger during the Early Cretaceous (Aptian stage, ~110–125 million years ago). Named in 1976 by Philippe Taquet, this ornithopod is distinct for the long, sail-like or hump-like structure along its back, likely used for thermoregulation or display.
Key Facts About Ouranosaurus:
Discovery: Two nearly complete skeletons were discovered in 1965 and 1970 in the Gadoufaoua deposits (Elrhaz Formation) in the Agadez region of Niger.
Physical Features: It had a flat, duck-like snout, a stiff back with long neural spines forming a sail, a long, deep tail, and a mix of bipedal/quadrupedal features.
Classification: Initially classified as an iguanodontian, it is currently recognized as a basal hadrosauriform.
Habitat: It inhabited a wet, fluvial environment (rivers and floodplains) alongside predators like Suchomimus and Eocarcharia.
Weight: Estimated to weigh between 2.2 and 4 metric tons.
Unique Characteristics
The Sail/Hump: The spines on its back were high, particularly over the arms, leading to debates on whether it held a, skin sail (like Spinosaurus) or a, fat-filled hump (like a camel).
"Brave" Name: The name means "brave lizard" in local dialects and the Greek word for lizard.
Unique Features: Unlike other iguanodonts, its fifth finger was not prehensile.

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.
