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)
