Resumo
| Descrición |
Lepidodendron sp. - fossil plant in sandstone from the Pennsylvanian of Ohio, USA. Plants are multicellular, photosynthetic eucaryotes. The oldest known land plant body fossils are Silurian in age. Fossil root traces of land plants are known back in the Ordovician. The Devonian was the key time interval during which land plants flourished and Earth experienced its first “greening” of the land. The earliest land plants were small and simple and probably remained close to bodies of water. By the Late Devonian, land plants had evolved large, tree-sized bodies and the first-ever forests appeared. Shown above is a fossil lycopod plant stem in sandstone. The specimen is partially coated with a crust of carbonized material that highlights the diamond-shaped leaf attachment scars. Classification: Plantae, Lycophyta, Lepidodendrales Stratigraphy: float from the lower Pottsville Group, upper Morrowan Series, upper Lower Pennsylvanian Location: loose piece from near the base of the Irish Ridge East Outcrop - roadcut along the eastbound entrance ramp from Rt. 60 to Rt. 16 (southeastern portion of Rt. 16-Rt. 60 interchange), north-northwest of the towns of Trinway & Dresden, northern Cass Township, northwestern Muskingum County, eastern Ohio, USA (~40° 09’ 13.56” North latitude, ~82° 01’ 29.37” West longitude) |
