Looks like a good site for bulk sampling for microfossils. I see a lot of bryozoan fragments. There are probably teeth and juvenile echinoids to be found. Have you ever screened this site?

Yes. Some small or broken shark teeth but no juvenile echinoids as of date.

Standing:

@Pleuromya: 11 Points (You desperately want some ugly Kainach Gosau fossils, aren´t you? ).

@Mochaccino, @Kasia, @will stevenson, @historianmichael: 5 Points each.

 

Next will be Pliocene!

You asked about this a few months ago.    Sicyophorus rarus  is the correct taxon. Protopriapulites haikouensis  is a junior synonym.

 

"The monotypic Sicyophorus was originally described as having an uncertain taxonomic affinity, but Protopriapulites haikouensis Hou et al., 1999, a junior synonym, was assigned to the Priapulida based on the arrangement of scalids on the introvert (Hou et al. 1999, 2004a)."

I’m such a dummy! I even rechecked my history to make sure I didn’t type the wrong name twice… needless to say I’m learning my lessons the hard way!

Thank you for always being diligent and informative!
