Incredible prep on that aussie species. I'm amazed at the similarities between the preservation of the aussie crab compared to the US species like Zanthopsis sp.
Thanks, i was impressed with his handy work. Prior to this him and I had only done 3 Diprotodon optatum jaws i got last year in 2014 together (3 in 6 weeks, that was a good start to the year ).
I love finding concretions, never know whats going to be inside!
