Ammonite tease

Recommended Posts

Billinthedesert

I was up in Cloudcroft on an errand and thought I might as well drive a few miles along Forest Service Road 5661, just south of the town. Here, Pennsylvanian sedimentary rocks are exposed along the cuts of the gravel road. You see a lot of pieces of fossils, but so far, anything remotely approaching whole has escaped me. Also, the rock does not seem to fracture in any kind of systematic plane, but rather at random and often right through the center of a fossil, leaving a thin section exposed and not a "half." But the stuff is there. It is frustrating.

And then this thing ...

Its always nice to get complete specimens, but in many many places that is not possibles or even rare.  At least your trying.  some almost good stuff there!  Just keep trying is all I can say.  and good luck.

Ooo, lookie who got a shiny new pick!

No ideas on the object below the pick?

That type of breakage in the rock can be very frustrating.

I have found many pea crab parts, but unless the little guys are positioned directly in the center of the small pieces of shale that this matrix breaks into, I will never find a whole one.

I akin the shale to be like safety glass. Just breaks up into little pieces.

Nice finds. :)

The second one could be the gastropod Straparallus.

And the third one looks very interesting. 

Any chance of close ups?

Tidgy, I left that third one up there, and now regret it.

I think I would go back and reclaim that piece, it looks different.

Looks like there are some good ammonites there, they just need a little tender loving prepperations.

 

If the sledge hammer doesn't work try an air scribe.

I second ynot, I'd go back and pick that up if at all possible. 

I regret you left it behind as well! ;)

Air scribe, eh? Wow -- a lot of stuff comes up when I Google "air scribe."

You could definitely lose a day reading all the helpful advice on prep tools like that here :D :  http://www.thefossilforum.com/index.php?/forum/170-fossil-preparation/

Kane, appreciate the link. I just watched a couple of Youtubes, and must say the air scribes seem to be noisy critters!

Yes, most are noisy.  Use ear protection or do the work in a sound dampening box.

This is the kind of thing one encounters in the strata I have been searching. You see them everywhere.

Well, I went back up and retrieved that piece I had left. Also found some more fragments as well as some small brachiopods, less than 2 cm.

Would love to find one of these big fellas intact.

Lesson: Do not try to remove too much matrix in the field!

On first glance, I was going to question the Pennsylvanian age, but with the additional pics I can see it now. Interesting stuff. Good thing you went back for that other item. I can't say what it is either, but it looks symmetrical so it must be something. I was going to suggest crab carapace, but if it's Pennsylvanian, I think that would rule out crab. Not knowing what something is is not a reason to leave it behind - it's a reason to take it home! It only has to look like something. I found a flower fossil that way once, only realizing what it was after examining it some time later.

The spiral thing looks like the cross-section of a snail, but I could be wrong.

Yes, I think all fossil collectors learns early on to resist the temptation to remove matrix in the field. I know what it's like dealing with crumbly, unpredictable rock. My local sites are all Cretaceous shale. Good preservation but frustrating to work with, to say the least.

Wrangellian, I was fortunate to fly-fish for pink salmon near the mouth of the Oyster a few years ago.  Vancouver Island is spectacular, even if the fossils primarily lie in crumbly Cretaceous shales!

It is nice, and is home to me, but NM doesn't look to bad either! Never been there.
