Is this from the Genus Cancer? Reminds me of Cancer novaezealandiae. Very rare at this site.

Not a Metacarcinus novaezealandiae , this is a different thing, to follow, will see...    :unsure:

Forgot that’s not cancer but Metacarcinus.

Did it used to be Cancer? 

 

So is the new one being studied?

Cancer novaezealandiae it was transferred to the genus Metacarcinus as subgenus by Nations (1975) and elevated to the genus status by Schweitzer & Feldmann in 2000 in his revision of Cancridae.

Regarding the Coleton's crab, it could be studied, but not yet, because there are some steps to follow before. It could be a new thing in my opinion, but it's early to say it .

Will see...

 My son bought this concretion from a friend of mine in New Zealand.  The rock is from the Canterbury Formation and Miocene in age.  My son is still in the beginning stages of learning how to prep and kinda beat this up while exsposing it.   I found out this crab is new to science and has no name.  I was in the process of trying to get it studied and then donated, (Alex Oso) but the museum in Christchurch seems to be closed and has not answered my email.   I told my son Im just going to hand it back to him and he can do whatever he seems fit.  I just dont have the time to get this done. Purty dang cool crab though!   My friend from New Zealand tells me he knows a guy who has one of these  so there are only 2 of these in the world!    Oh, this rock measures 4 inches across and it still needs some work.

My latest Tumidocarcinus from New Zealand. That small claw was hard to prep as it looks like it collapsed during rock forming.

If you missed the other thread, here’s my current project. Very sticky. Only mm sized bits of matrix will come off most of the carapace and the legs (where they are black). So it’s remove matrix till you are close then microjack under the scope. 40-50 hours in so far. About 25 cm across

I'm not saying you made a fake, it's just an impression. The lateral spines have no consistency or regularity.

It may also be a pathology

No, I don't know at the moment being, but not Scylla and neither Portunidae in my opinion.:zzzzscratchchin:

 I could have an idea, but the front and lateral margins should be a little more worked yet .
