These are pictures of fossils stumbled upon by my son and me.  They're currently being examined by pros (Doug Erwin and Emma Smith).  We think they're Namacalathus.  What do you think?

 It does rather resemble a series of cross-sections of Namacalathus. Where was it found and do you know the age of the rock?

It's at 39.084523, -113.715651W.  if that shows up in China, it's Google maps' fautl.  Just change the sign.  The age is from a geologic map for that part of Utah that doesn't have good resolution.  I'me pretty familiar with limestone from other locations, and the age is right at the Ediacaran-Cambrian interface.  It's the most easily accessible site imaginable.  You can drive to it.
