Sanity check: it's a Nautilus, right?

Recommended Posts

So, I found this today in the Paleocene Aquia Formation of Maryland.  Obviously it can't be an ammonite, because they were already extinct.  It's a Nautilus steinkern, right, not some sort of gastropod?  

 

Thanks!

Matt

Definitely a nautilus. I can see the simple, slightly sinuous sutures of a nautilus that separate the chambers. Nice specimen! 

 

By the way, isn’t the Aquia Formation Paleocene?

Yikes, that's embarrassing. Post corrected to "Paleocene".

I have made hundreds of trips to multiple Aquia exposures and never even seen a fragment of one. If you decide to get rid of it the Calvert Marine Museum would love to have it in their collection.

I found a big one years ago in the Aquia formation near Central Avenue, I donated it to the Smithsonian. They're extremely rare.

All the cliff falls must’ve exposed this one. Though it’s a great (once in a lifetime) find the risk to find it (and keep that life) was probably pretty high. I’d stay away from those unstable cliffs till they dry up a bit.

I was wondering how rare that is because I've never seen one from the Aquia before.  Nautiloids rebounded in diversity in the Paleocene but they aren't common finds anywhere from that time.  There are occasional finds from the Midway Group in Texas and Arkansas.

Congrats on the amazing and rare find. Also, kudos to you for contacting the Calvert Marine Museum and offering it to them.
