Jince Fossil Locations 


                                             Jince fossil site

Arthropod living at the bottom of the Paleozoic seas has increased by as often forced to undress tight chitinous shell and thus in contemporary sediments found a number of positive and negative impressions of head shields, rugged fuselage and tail shields of this prehistoric animal.

These prehistoric animal, who lived in our territory before 300-570 million years, especially during the Cambrian and Ordovician, made famous in the 19th century, Joachim Barrande and they became famous his.

On numerous outcrops of weathered slate, Jince locations can trace most four kinds of Paleozoic trilobites. Distinctive head and a small tail shield has long narrow cheeks adorned with thorns Paradoxides gracilis. The narrow body is fitted on the sides of the rear-facing spines, tail section is topped by Article shaped blades. Ellipsocephalus Hoff is a small species with a semicircular head and expressive narrow eyes, posunutýma to the edge of the free cheeks. Its tail shield is composed of only two relatively broad articles. Ellipsocephalus probably lived in calm waters and perhaps also because often find fingerprints entire bodies of trilobites. Whole can often find fingerprints kind Conocoryphe Sulzer. Has a distinctive rim around the head shield, wide body and completely lacks eyes. Probably lived his entire life in the mud and welt on his head burrowed in the bottom in search of organic residues, forming his food. Ptychoparia striata has a wide body and a distinctive edge. Unlike kind Conocoryphe but head adorned with large eyes and the hull is completed with a larger tail shield.

Dinosaurus ?

Praha and its surroundings is a geological point of view very interesting. You can follow the development of our country from starohor - Proterozoic more than 600 million years ago until the geological presence.

Starší prvohory - Paleoproterozoic strata, which form the so-called Barrandien are revealed in a unique way.Prague and its closer and wider environment is rich in fossiles.

Fossils of trilobites are most interested me. Therefore this blog will be made after some paleontological
localities of the Ceska Republika, where these fossils are. Dinosaurus unfortunately, there probably is not but is otherwise rich in fossils Czech.
