Some finds from my Spring 2017 collecting season. Pictured specimens were collected in situ from the Hungry Hollow Mbr. of the Widder Formation (Middle Devonian, Hamilton Group, Southwestern Ontario). Due to file size restrictions I'll split the posts by phylum.

 

Prone Eldredgeops (unprepped). Specimen consolidated with 6:1 water to PVA solution in field. Reverse side later coated with Acryloid (Paraloid) B-72 to stabilize matrix.

Prone Basidechenella (unprepped). Consolidated as above. Missing lateral border and genal spine on one side of cephalon. This genus' exoskeleton preserves painfully thin making it a pain in the pygidium to collect.

Gilbertsocrinus (surface collected). Inflated crinoid calyx showing tegmen, some spine regeneration and attached columnal segments.

Dolotacrinus (crinoid, unprepped). Trust me... it's in there.

Great finds! :wub: 

We don't see this material on the Forum much - Thanks for posting it. 

Hope the rest of your collecting season is as productive!

It is incredibly tough to find an even remotely complete Basi at that site (at least for me). One mostly will find a few pygidia and other disarticulated fragments. The only other place I've ever seen that has pulled full Basi trilos from Hungry Hollow has been on the UMMP database. That trilo had to be a trip-maker! I mean the blastoids are cool and all, but... that trilo is fantastic. In terms of the blastoids, the Nucleocrinus looks nicely inflated, too. :fistbump:

Very nice basi (its all relative). A complete Basidechenella from Arkona is certainly a trilobite that is still on my bucket list to find. Unfortunately this is the best I have managed to find there so far (once prepped I think yours will be much nicer. As you can see my example is incomplete and in rough shape. The preservation is tentative at best wanting to disintegrate if you look at it too hard. The exoskeleton is extremely thin and cracked from crushing and weathering. This was found excavating on the North bank on the section just past the old bridge footings about 10 feet above water level.

The bugs are nice but the echinoderms are awesome.

Thanks!
