Looks like you keep finding really interesting critters! I do retrace my footsteps commonly and lots of times just stop and do a 360 and go down on one knee to look closely at the surface/outcrops but it could be just my peculiar habit to compensate for needing new glasses!

Thanks for all the great shots!

Regards, Chris

Hey Chris. I have always known I needed to slow my approach to outcrops...it just never happens. :) Too darn excited to see what treasures the slopes are holding.

Pretty cool! :goodjob: Wish I had known about that place when I was a kid. :unsure:

:popcorn:

Come on Tony, when you were a kid, the ammonites were still swimming!

That's why I know where all the good fossils are-- I saw them get buried when the animals died!! :P

Tony

PS Mike-- still enjoy the trip reports and wonderful finds!! Please keep them coming.

I grew up in NM and am back there several times a year for months at a time. For years I've been meaning to hit up the Puerco. Your finds are fantastic and are making me wonder why it's taking me so long get out there! Definitely on this year's hit list.

Definitely make some time to get out there...it's good for the soul. :)

I decided to hit the Puerco quite early on Saturday morning...

...as I wanted to hit an outcrop in search of Collignonicerids.

To better understand the ammonite zones of the local geology, I was hoping to find C. woollgari. These impressions in sandstone...

...were and exciting confirmation. Now, which subzone?...not sure yet. This scaphite impression...

post-11220-0-26475900-1468866824_thumb.jpg

...may help answer that.

After a spending some time in the lower Carlile shale, it was time to climb back up into the C. praecox and Prionocyclus hyatti ammonite zones of the upper Carlile.

The first finds were Spathites puercoensis...

...as the temps began to rise, this guy was scrambling for shelter...

post-11220-0-02116100-1468868404_thumb.jpg

...and I headed for the truck. As I made my way, this Placenticeras pseudoplacenta made me pause for a moment...

post-11220-0-62097300-1468888155_thumb.jpg

...and ended a great collecting trip. As I trucked down the dirt road to the highway, Masticophis flagellum was there to bid me farewell.

'Til next time,

Happy hunting!

Awesome photos and trip, Mike. I may, or may not, have 'goosed' you in the leg while you were taking the photo of that tarantula.... :o:P

I like the shark teeth as well...unfortunately the sandstone refuses to give them up complete.

I had been reading about a Prionocyclus percarinatus ammonite zone that separates the Collignoniceras woollgari and Prionocyclus hyatti ammonite zones (Cobban, 1984 & Kauffman ET AL. 1993) in the Carlile Shale...

Carlileshale.jpg

...so as part of our 4th of July (actually the 3rd) family adventure, we hit the Puerco for a bit of exploring...

chicenandi.jpg

...small shout out to that BOB stroller, now dubbed the Carlile Cruiser :)...

...I searched a concretion bearing horizon that, in the past, seemed barren of ammonite fossils (most likely due to my level of patience :wacko: ). Within in minutes I began finding samples of Mytiloides...

...Further down the ridge I found a small piece of an ammonite weathered from a small, crumbly concretion. Nearby was a similar type of small concretion. A few hammer whacks and my first Prionocyclus percarinatus Collignoniceras percarinatum.

percarinatus1.jpg percarinatus2.jpg

Hooray for biostratigraphy. :D

EDIT: P. percarinatus reassigned to C. percarinatum (W. J. Kennedy, W. A. Cobban, and N. H. Landman. 2001)

 

Since finding the specimen above, I have learned a few things. The C. percarinatum ammonite zone is no longer valid and was changed to the Collignoniceras praecox ammonite zone for the Western Interior Seaway of North America (Merewether et al. 1998). This ammonite zone has yet to be documented in New Mexico...at least for now. :)

 

I headed out the Puerco to investigate another site in search of this undocumented ammonite.

 

IMG_20161022_101131898.jpg

 

This site, initially, seemed barren of fossils though it looked the part...

 

IMG_20161022_095459608.jpg

 

...and then I noticed a layer producing small nodules containing bivalves...

 

IMG_20161022_164946.jpg

 

...and in following this horizon, came away with a few handfuls of fossils...

 

IMG_20161022_095408913.jpgIMG_20161022_123824976.jpg

 

...some of which are exactly what I was after...

 

IMG_20161022_095619177.jpg

 

...Collignoniceras praecox! Now it is off to the museum for me and my finds. :D

 

I hope you find your adventures as rewarding...

 

...Happy hunting!

Hey! Way to go, Mike! You are turning into the Sherlock Holmes of the fossil set :D Are you thinking about documenting this zone now, or at least together with someone else?
