Distal caudal chevron bone from Stegosaurus sp. (Morrison Formation, Late Jurassic); specimen: Rare Stegosaurus Chevron Bone; treatment: Conservado; condition: Natural.
AI-assisted summary
Description from the seller
This is a genuine distal caudal chevron bone from Stegosaurus sp. (Family: Stegosauridae), one of the most iconic herbivorous dinosaurs of the Late Jurassic period.
Chevron bones—also known as haemal arches—are paired bones located beneath the tail vertebrae of many reptiles and dinosaurs.
These bones helped protect vital blood vessels and supported tail muscles, contributing to both tail mobility and defensive capabilities.
In Stegosaurus, the tail may have been used as a weapon (the famous “thagomizer”), making chevrons a key part of its functional anatomy.
This specific specimen is from the distal (far) end of the tail, a region where chevrons are particularly slender and delicate, and thus rarely preserved or found intact. Fossils from this portion of the skeleton are uncommon, making this a rare and scientifically interesting piece for collectors, educators, or institutions.
Unearthed from the Morrison Formation, a world-renowned Jurassic fossil bed in the western United States, this bone is approximately 150 million years old and shows excellent preservation for its type.
Species: Stegosaurus sp.
Class: Reptilia
Family: Stegosauridae
Geological Formation: Morrison Formation, Utah

Seller's Story
Don & Donna Fossils finally moved to Spain.
We are a Don & Donna Fossils, a couple united by the love of exploration, field research, professional preparation and museum display of fossils from all over the world.
This formula, combined with a desire to improve, makes us a winning team dedicated to our Fossil World.
Larisa is been passionate about fossils since was a child. Her strengths are perfectionism, perseverance and creativity, hence her ability to work and prepare these fossils as authentic, unique and aesthetic as possible. The pieces with which she is famous and which she boast the most are spiny ammonites.
I, Don, started fossil hunting in 1987, going from a passionate collector to a professional preparator and researcher. In all these years I have traveled searching for fossils in many parts of the world.
Our fossils are present in private collections in the United States, Singapore, Taiwan, as well as in prestigious museums in the Uk, China and Japan.
Quality in the preparation of the material and seriousness in managing the shipment in the best possible way distinguish us.
