Ammonite or Nautiloid?

I was given this as a gift as a child. I gave the other half to a friend some time ago.

It has complex suture lines,  so it is an ammonite.

Yes, it could well be Moroccan, there are certainly many like this from here. 

But also from elsewhere, so i wouldn't bet my tortoise on it.

Well OK, but would you bet your beard?

Very typical of the split and polished ammos from Madagascar of which I have many.

Morocco--Madagascar (Missed it by that much--got the right first letter.) :P

 

I should have known Madagascar as I have a few from there but somehow I never think of that island nation and Morocco always comes to mind first.

 

 

Cheers.

I've nearly made that mistake a number of times - both M names and both have flooded the market with processed ammonites!

Not to say for sure, but I'd have to go see for myself.

Not likely -- The sutures seem to be more complex than those of known California specimens. The sutures of ammonites are like fingerprints, only they are not different for each individual but for each species instead. That's how you can tell which you have just by looking at it. Unfortunately you need the entire left or right half of the suture exposed to identify it down to species, unless you know the location and the rock it came out of. You can study ammonites for your entire life and never know everything because there are so many species, but not as mind-boggling as trilobytes which are a whole different kind of nightmare.

Mark.

 

Fossil hunting is easy -- they don't run away when you shoot at them!

True, Welcome to the forum:

Even though Nautiloids have simple septa,  they certainly can show_off.

Awesome! Cephalopods are so unique and amazing. I always find joy in them.
