Hypostome Identified

Recommended Posts

Steve D.

Hello! 

 

I just came across almost a complete hypostome and a larger wing of the mouth line on a smaller hash plate. Didn't know it until I broke down the matrix. The more I chip away at the plate the more minor trilobite pieces I am finding...which is not unusual. Is there any suggestions on how to categorize and store these??? 

 

Sorry for the snarge picture.... Still need lighting in my new manpad.

Great photo to zoom in on. The trilo bits I find are also darker and stand out as your's do. You can store in bubble wrap or foil, I use rags sometimes. Mostly I just leave them out for further enjoyment. Nice find!

Herb is correct. Hypostome of an Isotelus. The ridges / terrace lines on it are quite distinct. There are some very good papers on isoteline hypostomes and their function.

These may require having an account with these sites. I acquired my copy through my uni library so I can't really comment on the quality of these copies.
