Ancient Seas, Northwestern Russia, Volkhov River, Ordovician, ca. 485 to 443 million years ago. A fantastic fossilized trilobite within a stone matrix that exhibits protruding defensive spines and "horns." This prehistoric "sea bug" is of the Hoplolichas furcifer genus known for the curving horns. The brown exoskeleton and the grainy texture of the cephalon and eye lobes contrast nicely with the white matrix! Some paleontologists posit that that the body armor and spines functioned as a defense against predators and perhaps for fighting other males during mating. Hoplolichas are one of the rarer and most spectacular of trilobite species. A fascinating reminder of the prehistoric creatures from the bottom of the seas! Size of fossil: 2" L x 1.25" W (5.1 cm x 3.2 cm); matrix: 4.4" L x 1" W x 3.375" H (11.2 cm x 2.5 cm x 8.6 cm); case: 6.125" L x 4.125" W x 3.25" H (15.6 cm x 10.5 cm x 8.3 cm)
Trilobites are a fossil group of extinct marine arthropods that form one of the earliest known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Devonian, all trilobite orders except the Proetids died out. Trilobites disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, roaming the oceans for over 270 million years.
