Vertebrate Fossil Discovery 5/5/13

Today's beach walk/fossil hunt revealed this treasure: a single rock full of beautiful bones. Because I am not an expert in vertebrate zoology, all I can really identify for certain is that these ARE bones. If you have information or an expert opinion, please comment.

The rocks really call to me.

This one was screaming!

The pinkish bones are so intriguing

I tried to find a tape measure, without luck.
I made one using a ruler and
 marks on a piece of paper.

The rock was about 24 inches long,
 8-16 inches thick

I was able to turn it over and photograph
 every edge and aspect of its surface.
Each face revealed more bones.

This treasure is readily available for discovery
 but I doubt that anyone sees as much of it as I do.

This aspect is most interesting.
Is it a pelvis, scapulae, skull? 

Isn't she beautiful?

The geology at this beach (Arroyo Burro, Santa Barbara, CA, USA) is so interesting. The fossils I find are in the very hard sedimentry layers that are below the level of the sand. The fossils only reveal themselves when the tides wash away enough sand to expose them.

Vertebrate Fossils of Santa Barbara

I am perplexed. Hungry for information on the fossils I have found, I google "vertebrate fossils Santa Barbara" and images I have taken from my own blog come up. I research "Miocene fossils of Santa Barbara" and find only evidence of invertebrates and whales, all embedded in shale or a different kind of rock all together. I am hungry for information.  I post this in hopes that someone will have some information for me.

My first fossil find, identified only as a bony fossil but an unknown part of vertebrate anatomy. 

I sent these pictures to the Santa Barbara Museum of Natural History several years ago and received no response.

I found this rock that greatly resembles a fossil egg on the same day I found my first vertebrate fossil. 

I began finding specimen after specimen on a particular beach in Santa Barbara. Every walk on the beach seemed to reveal a new find.

This is me in front of a particularly rich fossil bed

My educational background is in human anatomy, anthropology, medicine with geology and paleontology as hobbies. I don't have a lot of experience with comparative anatomy so I am having a hard time figuring out if these are mammalian, reptilian or ichtheoid  (bony fish) fossils.

If you, my future reader, have any insights, please comment.
