Fish Prep

Recommended Posts

Our own TFF member StevenDennis was brave enough to let me work on a fish from his collection last week. It is an amazingly well preserved fish from South Texas. The matrix is an extremely hard sandstone. Bulk removal required my CP9361 with detail work done with my Aro. The dorsal and pelvic fins are VERY small (I almost scribed through them without knowing it!) Caudal and pectoral fins are a bit larger. It looks like a prehistoric herring!

Here are before and after pics.

Very nice, I enjoyed seeing that one.

Human beings, who are almost unique in having the ability to learn from the experience of others, also are remarkable for their apparent disinclination to do so. - Douglas Adams, Last Chance to See

Now, we're trying to find an ID for it!

I believe I have nailed it down to the Upper Cretaceous San Miguel Formation (based on approximate location and descriptions of the formation). I don't have much in the way of reference material for South Texas fossil though...

Apsopelix anglicus ?

Halfway down page....http://oceansofkansas.com/FieldGuide2.html

:zzzzscratchchin:

I have attached a poor photo of an obliquely compressed Apsopelix sp. (Id by Mike Everhart) that I collected from the Britton Formation for comparison.

I have the paper at home in which Apsopelix is described. I'll consult it this evening.
