Unknown bone(?) from Pliocene Pico Formation of Southern California
Crusty_Crab posted a topic in Fossil ID
This was found in the Pliocene marine Pico Formation of Southern California. I'm leaning towards a marine mammal but I'm not even sure if this is bone or part of an echinoid test.- 11 replies

Marine Fossil Three Serrated Edges Late Pleistocene to Pliocene Southern California
MightyPretzel posted a topic in Fossil ID
Happy holidays everyone. I would greatly appreciate help identifying the following specimen. It was collected in the Santa Susana Mountains of Simi Valley, Ventura County, California. It came from the Saugus or Pico Formation. Saugus is late Pleistocene to late Pliocene while Pico is middle Pleistocene to Pliocene. My uncertainty regarding the exact formation arises from the fact that (1) it was float material already weathered out of the formation it came from and (2) based on limited research and knowledge, I believe there has been a lack of consenus regarding differentiation of the two formations (see recent work by Richard Squires et al. in Valencia and R. Squires in Newhall). I assume it is marine since all of Pico is marine and Saugus is non-marine to marine. At first I thought it was a shark tooth when I picked it up but I threw that thought out the window when I realized it had three serrated edges. Measures 22 millimeters long and 6.5 millimeters wide. It is 4 millimeters tall on one end and 9.5 millimeters tall on he end that has the needle structure. There are three to four 'bumps' on both long sides on the end with the needle. The bumps look evenly spaced. I can and will do my best to provide additional info if needed.- 13 replies
