Hi Ryan,


Good stuff, I'm pretty sure that's a tiny belemnite, looks like there might be some alveolus or is that just matrix stuck on at the blunt end?
 

Not 100% sure but the last one looks belemnitic too, perhaps compressed stem region of  a small Hibolithes

I had my first go at specifically targeting mini fossils (not so much micro as they can just about be seen by the naked eye and gathered by hand). I took about a kilo of gravel/sand mix from various points at an oxford clay site then picked through it.
 

All scales are in mm.

 

Some things are easy to ID - tiny belemnite - 6mm long but perfectly formed.

 - I actually found even smaller ones than this but they dont look so recognisably belemnite shaped. The really tiny ones are somewhat featureless straight rods from what I have seen.

 

Tiny crinoid section - again just a scaled down version of the adult in appearance.

Now for something odd though it looked familiar from seeing it in a book somewhere but I cant remember where - doh! Its very 3d - its like a flattened 'jack'.

Piece of vertebrate bone - oddly the second such piece from the exact same spot that look near identical in shape - I did wonder if they could be ear-bones (Otoliths)?

Next I found a surprising abundance of sections that look like this:

stinger_point.jpg 

 

I am in two minds over those - they remind me of ray stingers but I also thought they could be echinoid spines? They are somewhat octagonal in cross section.

 

This next one is pretty weird - I am thinking some sort of fish lower jaw or palate? Second picture from above showing the gap between the two ridged sides.

Final one is also fishy :p I cant decide if its a fossil or part of some fishing lure though it seems a bit small... Nice spots though.

End on.

Thanks for looking - any suggestions towards IDs for the various unknowns gratefully accepted Smile

 

Regards,

 

Ryan

Ryan, certianly is small stuff. The prefectly formed belemnite must be the smallest I have ever seenThumbs Up
Have a nice day :0)

Yes - I think thats the most likely as I have never found any ray teeth at the site but have found a few dis-articulated echinoid plates. Oddly I didnt find any plates in my sample but judging from the number of spines they must have been relatively common.

Thanks Julian - good thought - it does look to have an interesting texture - I like the traces of original patterning and colour - looks like the crab would have had good camouflage.

 

I will try and get some better pictures of the bit tentatively ID'd as fish jaw at lunch.

 

Regards,

 

Ryan

Ryan, could the jack-shaped one be a worn pyrite crystal? - there are a lot that shape in the Yorkshire Lias shales.
 

The penultimate one might be a ray tooth element - Myliobatis sort of thing (I know nothing about fish teeth though!).

Yes - I think your right - it certainly is a tough little piece.

I think it would have used the ridges in the same way a ray does to crush its food but the alignment of the crushing surfaces is on a V shape where the ray teeth I have seen are horizontal?

Talking from a position of near-total ignorance, could that be the occlusal side?


Someone e.g. Bill or Dave will have a much better idea.

Heh - pass - I have no idea - I looked at a few ray tooth sets and jaw pads but couldnt find a match of this to myliobatis?

Hey y'all
Interesting fossils Ryan, its not a Myliobatis, nor does it look like any ray tooth i know of. I'm completely flummoxed by it, i have no idea what it is lol.
Thanks

Makes me feel a bit happier at my own confusion :) More pictures of it:

Now for tonights bits and pieces. Is this a really really tiny belemnite? 4mm.

reallytinybelem.jpg 

 

Nice chunk of mineralised bone.

 

[attach:fileid=http://www.discussfossils.com/forum/uploads/1549/partminbone.jpg]

 

Is this a bumpy section of budding crinoid?

Next maybe some piece of crustacean?

 

oddity1.jpg oddity2.jpg 

 

Finally another weird one - looks like a circular calcite core but odd shaped.

Any suggestions gratefully received!
