Plantguy Posted August 11, 2013 Share Posted August 11, 2013 (edited) Cool critters all! I've got a couple Cambrian bugs that I am very fond of but here's a trace fossil that I dug out of the Bonanza King Formation while doing some mapping near Shoshone/Death Valley area, California some 30+ years ago. It has an unknown factor that has always intrigued me--what made it and how did it do it. I posted a shot of it on the forum some time ago but Scott just ID'd it for me in a blink of an eye last night and sent me the article describing what I had---thanks again Scott! Its a 11 cm long segment of a vertical burrow called Skolithos bulbus. Its all I have of a once larger segment that just seem to go on and on perpendicular to the thin shaly beds in the outcrop. From the 1975 article (PLANOLITES AND SKOLITHOS FROM THE UPPER PRECAMBRIAN-LOWER CAMBRIAN, WHITE-INYO MOUNTAINS, CALIFORNIA by Stephen P. Albert) http://decapoda.nhm.org/pdfs/33143/33143.pdf the author describes these critters in an area north of where I found my example. They are not sure what the little segments/bulbs represent. Possibilities include turn around areas which allowed the organism to adjust its orientation in the burrow or they may have been brood or storage areas.

PRK Posted August 14, 2013 Author Share Posted August 14, 2013 (edited) So I guess I will. Not my FAVORITES, but I like 'em I collected these back when Bob Harris was the only game in town. There was no "pay-to-dig" back then. ELRATHIA pile Edited August 14, 2013 by PRK Link to comment Share on other sites More sharing options...

trilobiteruss Posted August 15, 2013 Share Posted August 15, 2013 This is my fav and it's also my only complete trilo! it is Olenellus schucherti. It is a sweet bug for sure but then I concentrate on Cambrian and Carboniferous bugs over other times, and so have a spot for these early trilobites. Very cool..
