Unknown and Uncertain Trace Fossils

The identifications of these trace fossils are uncertain

unknown horizontal burrows in a turbidite sandstone with dish structures Eocene Point of Rocks Fm Salt Creek, Temblor Range San Joaquin Valley, California

possibly Asterosoma, more likely Teichichnus Miocene Webster Sandstone (Monterey Fm) unknown well, Midway-Sunset oil field San Joaquin Valley, California

insect burrows? (Naktodemasis?) Piru Gorge Sandstone Member Miocene Ridge Route Fm (non-marine) Old Templin Highway (near Castaic) South margin San Joaquin Valley

Unknown insect trace (Ancorichnus?) Fisher Springs Sandstone Member Miocene Ridge Route Fm (non-marine) Old Templin Highway (near Castaic) South margin San Joaquin Valley

 

Identifications by others that we disagree with

Planolites in core Miocene Naricual Formation unknown well in Eastern Venezuela Basin (Called Macaronichnus by Quiroz et al, 2010, but burrow fill and matrix are not the same)

Scalarituba in outcrop Miocene to Oligocene sandstones Algeciras (southern tip of Spain) (Called Neonereites in Wikipedia, but it best fits the description of Scalarituba)
