Authentication of Australian Crinoid Fossil (Jimbacrinus Bostocki)

Recommended Posts

Peter Stahlberg

Hello! I'm new to fossil collecting (as well as this forum) and have bought my first fossil today. Being completely inexperienced, I thought I'd try asking folks on this forum whether the fossil I bout is authentic. I am somewhat skeptical of this crinoid fossil's authenticity given how well the crinoids themselves seem to be preserved in the substrate. They almost look like they're made out of potting clay and are very crisp. Could anyone with experience give their input? This fossil was a significant investment so I'd like to at least know I got what I paid for! Thanks in advance.

I think real. 

Jimbacrinus is one of those fossils that often doesn't look quite real. 

Hello, and a very warm welcome to TFF from Morocco.:)

I think that's a very nice piece.

Everything looks about right to me. Looks like the right coloration and preservation. From Gascoyne River, Western Australia? Very cool piece. I like these crinoids a lot.

Alright thanks for the responses. I did the rudimentary teeth tapping test and it felt like pretty solid and real rock. It was also slightly crumbly/flaky-- not sure if either of those hold any value... but that's about all I can tell.
