Summary
[edit]DescriptionRhizocretions in paleosol (Eskridge Shale, Lower Permian; Manhattan, Kansas, USA) 1 (25683090561).jpg |
Rhizocretions in paleosol in the Permian of Kansas, USA. Rhizocretions are terrestrial fossils consisting of irregularly curvilinear, often downward-branching structures having a subcircular cross-section. They represent the position of roots of ancient plants. Rhizocretions are also known as rhizoliths or rhizo-ichnomorphs or vegemorphs, or simply “root traces”. The root word “rhizo-” literally means “roots”. Stratigraphy: Eskridge Shale, Lower Permian Locality: roadcut on the northeastern side of Anderson Avenue, just east of Scenic Drive, western side of the town of Manhattan, southeastern Riley County, northeastern Kansas, USA (39° 11' 25.81" North latitude, 96° 38' 21.74" West longitude) |
