Fossil compressed on only one side

[deltav2]

[deltav2]

So flat on the compressed side that it looks like it has been sliced 

[JohnJ]

When this nautiloid was embedded in the bedrock, the exposed part was eroded flat to the surface.  When freed from that bedrock, the protected 'other side' was unaffected.

Nice find.

Any chance that it has been preserved more or less completely and just "sliced" by weathering, wind erosion etc.? I am noticing many protruding clasts on the "sliced" surface.

Well,the whole piece was exhumed at one time or another,and subject to erosion

I agree. My point above was that it was eroded level with the bedrock surface.

those protrusions are alveolina, also its probably happened during its preservation because it looks too flat for it to have gotten weathered after preservation

I can only think of one related fossil (an ammonoid, not ammonite) where the flat side is a natural feature, and that would be Maclurites from the Ordovician. In this case, to my eye it looks like erosion occurred when it was already fossilized, and somehow it got separated from the rest of the bedrock.

Maclurites was a gastropod.

now that i look at it, it looks more like it eroded after preservation but its strange that none of my other fossils from the same region show any signs of wind erosion, only compression

Deltav,those Alveolina could have stratigraphical  significance,as you perhaps already know

Where did you find your piece,Damman,Al Kharrara maybe?

Yes the formation where i found it is called dukhan alveolina limestone due to the abundance of it

 

[doushantuo]

so  your piece is about "middle Eocene"( Umm Babb Membe(pars)

If you could see what shade of red my embarrassment has created! And I even knew that... I've been out in the sun too long!  

 

I'm going to sit in the corner with the pointy hat for now.

Ha! 

If I could count on one hand the amount of embarrassing mistakes I've made on this forum, I'd have an awful lot of fingers. 

[doushantuo]

 Same here.  If I got half a nickle for every mistake I made here, my wallet would reach to the Coalsack Nebula.

I just edited a post, and wouldn't you know it: as per usual, I mentioned the cause for the edit.

AND I Typed: "Tpoy agian". Seriously

Are you in big trouble if you cant type "typo"?

YES

[FranzBernhard]

That´s half of the fun here. Making mistakes and learning from them.

"It looks like..."

"It could be..."

etc.

[doushantuo]

totally agree
