All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity **Please note: Some fossils maybe propped up for photo purposes** Specimen: Large Cidaris urchin Age: Jurassic Location: Morocco Size (picture scale cube=1cm): 43 x 41 x 29mm (1.69 x 1.61 x 1.14 inches) Echinoids, or Sea Urchins as they are better known, have been present in our seas for around 450 million years, and are still largely present today. Their name derives from the Greek ‘Echin’ (‘Spiny’), referring to their protective spines, and ‘Ooid’ (Egg-Like) in reference to their globular shell, or ‘test’ as it is known. Echinoids are part of a much larger group of animals known as the Echinoderms (‘Spiny-Skins’), which also includes the Asteroids (Starfish), Holothurians (Sea Cucumbers), Crinoids (Sea Lilies and Feather Stars) and the Ophiuroids (Brittle Stars). Sea urchins move slowly, crawling with their tube feet, and sometimes pushing themselves with their spines. They feed primarily on algae but also eat slow-moving or sessile animals. Their predators include Sea Otters, Starfish, Wolf Eels, and Triggerfish. ACTUAL AS SEEN: The image shows the EXACT unique specimen you will receive. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device.

Now-a-days it generally means ‘The remains or trace evidence of prehistoric life’. The study of fossils is called palaeontology; someone who collects and studies them is called a palaeontologists. Fossils can be as tiny as a grain of pollen or a seed for e.g. or as huge as a limb bone from a giant dinosaur. For animal or plant remains to have become ‘fossilised ‘, they must go through a certain process that preserves them for up to millions of years after they have died. Usually it is only the hard parts of plants and animals that survive this long process. How Fossils Formed The most common method of how fossils formed is once an animal or plant dies, it falls to the ground, and is covered by sediment. This is often sediments brought from water. In the diagram above, the ammonite died in a river, and sediments over time covered the ammonite (shown in the second diagram). Finally after hundreds of thousands, or millions of years, the land is eroded and the fossil can be seen. Of the vast amount of prehistoric life that died, it is only a tiny amount that has survived the fossilisation process. The conditions when the majority of life died were just not right at that time, to preserve them. Most fossils are found in sedimentary rocks which were formed from the sediments of rivers, lakes and seas. The majority of the animal and plant fossils we find today, had originally died near these areas, got broken up and deposited on the beds of the rivers, lakes and seas. The sediments covered them and over time some of the layers grew so thick that many of them got crushed. The sediments compacted and over time and turned to rock. The rocks shifted, moved and became exposed to the elements. This process can take up to several hundred million years. Now as the rocks erode or are quarried for e.g. the fossils become exposed and can be collected. The Best conditions for Fossilisation 1. The quick burial of animal remains in moist sediments. This prevents scavengers from eating and bacteria from decaying them. 2. The quick burial in volcanic ash. Many dinosaur bones in the American west have been found buried in volcanic ash. 3. The presence of hard body or plant parts, teeth, bones, shell and wood for example. 4. Unchanging temperature conditions. 5. Ground water that is heavily mineralised. 6. Sediments that are very fine make a better burial than coarser gravels. 7. Calm conditions, so that remains are not broken up (by wave or currant action for example).
