Fossil Imprint - Near Pipeline Road New Mexico


BillG

Recommended Posts

Today I drove to Pipeline Road by way of Cabezon Road, by way of NM550 from I-25. I found this particular imprint almost common in the rocks near the Windmill site. The imprint appear as wavy depressions radiating somewhat like a fan. My guess is they are from some kind of large bivalve but I found no shells anyway near this large. I forgot to put a coin next to each but they measured in inches (not small) :( .

I've attached three different examples.

This is just a far out guess, the third picture looks like the top of a coral, but that's my amateur stab in the dark.

I don't know the age of your site but for comparison look for a picture of Oxytropidoceras on google.

What is the time period of the rocks ??

Correct. Pictured in Bill's original post are Prionocyclus (novimexicanus or wyomingensis) impressions from the Juana Lopez Member of the Mancos Shale. These impressions, along with those of Scaphites, are common within this SS member.

Bill, there are ammonites (as well as Ptychodus teeth) around so I would not give up. Best of luck.

Nice ammos.

Is the windmill site one of those turbine fields? Last year, we flew over many turbines east of Albuquerque. I wonder how much rock is being exposed as they excavate for the towers and roads?

Context is critical.

"The Windmill Site" is a lowly homestead windmill perched on a hill. The field of turbines SW of ABQ is pretty impressive.
