This type of brittlestar is quite representative of the Ordovician of the South of Morocco.

Its orange colors come from the limonite (iron oxide) that is the product of the oxidation of the original pyrite that mineralized these fossils.

A physical certificate of authenticity is provided free of charge with every fossil we sell. This is our lifetime guarantee.

Who we are
Jurassic Dreams is the world's largest online dinosaur fossils store, unrivalled as the most reputable source for authentic fossil specimens. We are the only leading online fossils store owned by an accredited paleontology expert.

With dozens of different species in stock from dinosaurs, reptiles, sharks... 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 consumes most of my time. What I like the most is discovering rare or new species (yes, I have done that). Obviously, recognizing fake and restored fossils is second nature to me. So you can be sure that every fossil in this website has been carefullyly 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 the exhibition and selling of the other numerous finds, which help keep funding the new expeditions.

A physical certificate of authenticity is provided free of charge with every fossil we sell. This is our lifetime guarantee. The certificate, individually elaborated for each fossil by Juan A. Poblador as expert geologist and paleontologist, contains an accurate scientific description and the certificate validity can be verified online at all times. In addition, a 100% money back guarantee is provided.

Apart from being scientifically accurate and providing authenticity authority, it makes for a great display picture in any collectors room or museum files.

The certificate of authenticity has the following features:

It is signed by an Accredited Geology and Paleontology Expert. The personal academic university verification code is provided on the bottom-right corner.
There is a unique Certificate Number on the top-right corner.
The Issued Date on the top-left corner corresponds to the purchase date at jurassic-dreams.
There is a Security Hologram on the bottom-center of the certificate. The number on the hologram must match that of the Certificate Number on the top-right corner. Removing the hologram destroys the paper and voids the certificate.
On the left side of the certificate the Scientific Description is displayed.
The validity of the certificate can be checked at any time at our website by providing the certificate number and issued date. Note that you have to write jurassicdreams without a hyphen in this case, which differs from the online store.
