Environment
Lithology: sandstone
Taphonomic context: paleosol
Habitat comments: the section is now "almost completely covered by vegetation" but appears to include "conglomerates with rounded, polygenic clasts, sometimes with imbricate bedding, alternating with thin layers of medium-coarse sand"
the fossils are "embedded by or maintaining traces of a whitish-yellowish sand with carbonate matrix" interpreted as a paleosol
the material ranges "from poorly preserved isolated specimens (very abraded and broken bones) to well-preserved ones, sometimes still in anatomical connection"
