A little more effort continues to pay off...

This crab has some issues, like a squashed and displaced face, but overall, I'm happy to add it to my collection.

The same day, I was fortunate to cross paths with my largest ammonite to date from the formation, a 6" example of what I believe to be Gaudryceras kayei. It too requred some restoration.

Cool constrictions and sutures on this one.

I also recently encountered some natural asphalt seeps in the Escondido Formation, 66 MYA. In a few spots, the Escondido tar sands gave up a few rare ammonites. First Coahuilites c.f. sheltoni

These asphalt ammonites are delightfully stenchful. If you put your nose against them and draw in a deep breath, you get a good woof of petroliferous acridity. Now, Pachydiscus c.f. mokobitensis

Truly amazing specimens Dan. Your collection must be stellar sir.

Did you find and prep that crab in one day???

Charlie - That crab was the product of 2-3 lunch hours sitting out behind the building with my scribe...good thing I'm able to run a 50 foot air hose outside.

Really nice crab! I probably wouldn't have even seen that specimen in situ. Really nice prep job.

marco, that's only because i have a 9 year jump on you in that formation, during which time i've trained my eyes to tune in on small scale subtleties. i'm often too late, and the resulting "explodacancers" are fragmented in the ground beyond recovery. i was lucky to find this one in bedded marl, so i dug wide, extricated a block, and hoped for the best.

Nice finds, Dan. Did you reconstruct those claws on the Dakotacancer or did you prep them out? Your early pics seem to show them missing at the "elbow".

good question, dave. the right claw was found loose and missing the movable finger. so that finger is epoxy. the left cheliped was eroded away from the merus on out, so i rummaged around my box-o-body parts and gave it a prosthetic. now it's the 6 million dollar crab!

richard, i'm pretty sure that's what it is. g. kayei is an extremely evolute form. although the inner whorl detail isn't well defined on this specimen, i have an evolute partial with the same sutures and constrictions which is obviously the same form. both this ammo and the crab took center stage in my Kco cabinet.
