Natural Science Forum / Biology / Paleontology / February 2006"Fossils From The Kettleman Hills, California" Is Now Back Online
I've finally re-uploaded one of my early, original paleontology-related web sites (with improvements in links, geologic data and fossil imaging--at least I hope they are improvements...) over at http://members.aol.com/Waucoba5/kh/kettleman.html --"Fossils From The Kettleman Hills, California." I'd already put back on the net my "Field Trip To The Kettleman Hills Fossil Field, California" at http://members.aol.com/Waucoba5/kh/kettlefieldtrip.html ; that's a virtual field trip to a number of the productive fossil sites within the Kettleman Hills paleo-complex. "Fossils From The Kettleman Hills, California" is a more-comprehensive web page which focuses on one of California's premiere Pliocene-age fossil-yielding districts--the Kettleman Hills region, of course, which lies along the western edge of the Great Central Valley. That's where the 4.5 to 2.0 million-year-old Etchegoin, San Joaquin and Tulare Formations yield abundant and exquisitely preserved sand dollars, pectens, oysters, clams, gastropods and curious "bulbous fish growths" (the fossilized bony tumors which afflicted many species of fish during deposition of the late Middle Pliocene Tulare Formation of the Kettleman Hills--such fossil specimens occur nowhere else on Earth, except in the Kettleman Hills; today, similar bony tumors afflict modern weak fish, angel fishes, cod and catfish), among other fossil types, that inhabited a complex system of marine, estuarine and fresh water habitats. > I've finally re-uploaded one of my early, original paleontology-related > web sites (with improvements in links, geologic data and fossil [quoted text clipped - 20 lines] > types, that inhabited a complex system of marine, estuarine and fresh > water habitats. I collected in the Kettleman Hills during a field trip in my undergrad paleo class. Great fun. But if there are directions or maps provided to the sites, I can't find them. And this would seem essential. I'd love to take my family there some time. ****I collected in the Kettleman Hills during a field trip in my undergrad paleo class. Great fun.

I'd love to take my family there some time. **** I have a database of US and Canadian fossil sites that I've been working on for about 30 years. Not that all of them work out. Many are mediocre, or inaccessible and some are just plain wrong in the original material. But some do work out. (No, the database is not on-line. I hope to get it up somewhere in the next couple of years) Here's what I have in Fresno and Kings county -- maybe it'll help?

But I do think I've been to a couple of those locations. Thanks. I don't know what "s15t18sr13e" means, though. Topo map reference? ***Thanks. I don't know what "s15t18sr13e" means, though. Topo map reference?*** Public Land Survey System coordinates. Read it as Section 15, t18 South, Range 13e. (Conceptually, the Baseline should be suffixed, but it is usually omitted). USGS topo maps (e.g. www.topozone.com) show ranges, townships and sections. There's software around on the internet to convert these units to something saner like UTM or lat long. May be prefixed by something like SouthEast 1/4th of Section .... My experience has been that PLSS coordinates are often incorrect and when they are wrong, they may well be off by tens or hundreds of miles. There's a good discussion of the PLSS in the Wikipedia -- http://en.wikipedia.org/wiki/Public_Land_Survey_System |
