These fossils are particularly precious to me, as they are found within 3 miles of where my house is located. Long before the Dinosaurs, The evolution of reptiles was spurred by the increasingly cold, dry climate of the late Carboniferous period.
Carboniferous Period, fifth interval of the Paleozoic Era, succeeding the Devonian Period and preceding the Permian Period. In terms of absolute time, the Carboniferous Period began approximately 358.9 million years ago and ended 298.9 million years ago. Its duration of approximately 60 million years makes it the longest period of the Paleozoic Era and the second longest period of the Phanerozoic Eon. The rocks that were formed or deposited during the period constitute the Carboniferous System. The name Carboniferous refers to coal-bearing strata that characterize the upper portion of the series throughout the world.
