What species are these echy's?

[RJB]

  Hello everybody.  I went through one of my fossil sheds the other day, something I have not done for quite awhile now, but I dug through some old boxes and totes and along with a lot of other fossils I ran into this box of echinoids.  I remember it was a trade and I remember they come from someplace in southern Cal.  The darker ones I want to say come from the Bakersfield area?  By any chance does anyone recognize these and cann help with any info would be great.  Thank you

Maybe Dendraster excentricus from pliocene

[DPS Ammonite]

Until prepped, wild guesses are probably all you will get. You need to see the petaloids and plates.

I did some playing around with some of the echy's from the Bakersfield area and ran them through the polishing process.  They are not very good, but I had a fun morning.  For the life of me I cant remember what the names for these are?  Also a pic of one I did about 25 years ago.  I hope this helps

They are Dendraster but I cannot tell you more with certainty (gibgsii ?)
