Cold Creek Fossils
Making the past Come Alive Welcome to Cold Creek Fossils. We specialize in high quality, professionally prepared fossil specimens using state of the art air abrasive technology. All specimens are origional none are casts or reproductions. Ordering Information Links Send a Message Click flag for a Geologic Time Scale Use. Read more about the great adventure which is paleontological in nature, like ancient archeaology, which is fossil hunting.
At Cold Creek Fossils, we want to make sure that you can buy the necessary artifacts related to ancient digs that you may need for your classroom, research, or thesis on archeology and dinosaurs. We believe that our quality cannot be matched, in terms of the technical precision of our digs and shovels. A good word counter is essential during examination of fossils on State lands and rivers, as you will need to obtain a permit and submit a well written yet concise entry on echinoids and sand dollars.
For your history listen, please read below the article which gives more information on an important historical dig archeological species: the trilobyte:
Before humans, before cows, before dinosaurs, the Trilobites ruled the world! What are Trilobites? you ask. They certainly weren't as massive as the dinosaurs, but they are a favourite among fossil collectors. The Trilobites became extinct before the first dinosaur saw the light of day, and are still extinct now. But they were very plentiful during the Paleozoic Era, 300 million years ago.
Trilobites (meaning "three lobed") were hard-shelled, segmented creatures that lived only in the ancient sea. They are one of the most diverse species ever, with over 15,000 known species. They range in size from just under a millimetre long, to 70 centimetres! Most Trilobites are about an inch long.

Trilobite fossils are one of the most well-known types of fossil animal groups, perhaps the second most well-known after dinosaurs, or third most after Ammonites. Trilobite fossils are quite common, varied over time (as new species evolved), and are found in many different locations around the world. As a result, trilobites are often used as "index fossils", which is to say that by identifying the particular type of trilobite found within a rock, it is often possible to assign a date to that rock.
When alive, trilobites were a group of arthropods (the same phylum that contains insects, crustaceans such as crabs and lobsters, spiders, millipedes, centipedes, etc.). All trilobites appear to have been marine living. Most lived in the seas, but there is some evidence that some species of trilobite may have lived in freshwater. During life, trilobites seem to filled many different ecological niches. Some trilobites were bottom-dwelling scavengers or predators, others were swimming plankton eaters, and there even appear to have been a group of trilobites which had a symbiotic relationship with sulfur-eating bacteria that provided them with food.
The very first trilobites evolved during the early part of the Cambrian period, perhaps 530 million years ago. They greatly diversified during the succeeding ages, but many species of trilobites were wiped out during the late Devonian mass extinction (364 million years ago). After this mass extinction, only one order of Trilobite (Proetida) survived, and this order, the last surviving Trilobites, died out during the Permian-Triassic mass extinction (248 million years ago).
