Unknown Ammonite

Recommended Posts

A couple of years ago, while on a romp through the Rio Puerco Valley, I found this ammonite. Since then, I have attempted to find a proper i.d. for this specimen through literature and documentation of New Mexico's Late Cretaceous ammonites. With very little luck, the closest resemblance were ammonites in the subfamily Puzosiinae, which are not documented from New Mexico. Today I decided to show the curator and the ammonite researcher at the New Mexico Museum of Natural History and Science.

Good news...they did not know what it was! :)...pretty exciting. Anyhoo, I have donated it to be studied but figured I would post it here as well.

Unknown ammonite from the Late Cretaceous (Cenomanian) Paguate Mbr. of the Dakota Formation - New Mexico, USA.

I doubt they'll be jumping on this right after lunch, but I will let ya'll know the results as I do.

Happy hunting,

-P.

That is just fantastic! I'm happy when I find a fragment of an ammo.

Thanks for the thoughts, Tom. Rhaeboceras has some similar attributes but shows up later in the Cretaceous (Campanian). I will pass along this idea.

Always exciting to find something rare! I dunno what it is either, but I'm relieved to hear they dunno either :P Hopefully they get to it after supper.

Thank you sir, I will do just that.

Very cool, Mike!

Thanks Tim. I don't find much that hasn't already been documented, so this is awesome!

I was pretty giddy when I left the museum...and now that I think about it...it was fantastic!

Roger, this is turning out to be my most exciting find. I always considered the ammonites I scour the desert for to be long ago documented...then this gem. I received an email from the museum expressing their gratitude for the donation with a note about, if nothing else, it being a new taxon from the formation. Yippee...science.

Yet another example that goes to show that just about all serious enthusiasts like yourself usually stumble onto something special as time goes on. Thing is you usually only recognize that once you establish contact with the profis. I had an ammonite displayed for 2 years in my collection which would still be collecting dust if a friend of mine hadn't recognized it for what it is. Since then I show all my question marks to those in the know.

Really nice specimen! It is always great when the specimen stumps an expert at first.

Just a little update on this ammonite. It is indeed a new species (in the process of being described) and "is the first record of Parapuzosia (Austiniceras) in the Cenomanian of North America".

A first for New Mexico was cool, but a first for North America is ice cold. :)

Excellent, Mike!

Congratulations on finding a first!

Most excellent! Will this be your first pfooleyi? You might consider requesting a painted plastotype of this specimen.

Well done, Mike. :fistbump:

I'll have to review some of my micro ammonites for similarities. ;)

Thank you gents. I am quite excited about this ammonite...my first, first. :) I never had an expectation for finding something new in a well documented formation. Just goes to show...leave no stone unturned. I am looking forward to the finalized description of the species... Parapuzosia (Austiniceras) Foleyi ?... :fingers crossed: .

Following this abstract a paper was written, submitted and rejected...it is not Parapuzosia

 

Rewrite...resubmit...                                                ...accepted! 

 

I have had the pleasure of reading the new article (unfortunately I do not have permission to share with you as it will be published later this month in Neues Jahrbuch für Geologie und Paläontologie) that describes this mystery ammonite as the first record of the ammonite Pachydesmoceras maroccanum from N. America, indicating a trans-Atlantic migration and the first Cenomanian record of the genus...still pretty nifty. :)

Congratulations Mike!  

 

Although it is always cool to have a new species, sometimes a situation like this tells a better story.  In this case the fossil documents both a trans-oceanic connection and a range extension in space and time for the genus.  A new species can be kind of a data point off on it's own, difficult to connect to other data points.  For example, new species are not really solid data points to use for correlation.

Thank you, Don. You are right, this ends up being a much more interesting story. :)
