What is the line between collecting and hording?
OregonFossil posted a topic in General Fossil Discussion
I'm behind on processing my finds. VERY FAR. In Oregon collecting is strictly regulated. However, Talus alongside roads is "fair game". I maybe have 4 or 500 samples from the Keasy and Pittsburg Bluff formations (the only one's I collect). Most are in some stage of having the matrix removed. I almost went back out today even though I have this back log. But I know the talus will weathered badly here in Oregon if not recovered during the dry season. Does having more samples than you can process in a year, mean you are hording and not collecting. I know this will be different for each individual, but just looking for perspective on the issue. The Dentalium pretty much shows at what stage most of finds get to before I stop. This one is about 5mm long and perhaps .5mm wide.

Keasey fm Dentalium. 10mm long, 10 pounds rock, 1000-6000' feet deep in a 800M layers of mud and slitstone (this is the very hard slitstone). Lots of small fossils in this formation. about 1 Dentalium for every 50 gastropods and 2/300 bivalves. I've included an unusual layer of small fossils found in the same rock, mosts less than 2mm.

Dentalium sp : a lutetian scaphopod from Fleury la rivière - Marne - France -
Hard to say what diameter is, as anterior end is squashed (about 9x15mm).

Trying To Figure Out What This Looked Like When Alive - Dentalium
6ix posted a topic in General Fossil Discussion
I have been trying to show the kids (and myself) what the animal from our 5mya shells probably looked like, we decided they are Fissidentalium as identified here.. http://www.gns.cri.nz/static/Mollusca/taxa/BM177.html After googling a heap I have come with them being known as tuskshells and dentalium (as coveted by american indians), but havent been able to find any video or photos of live ones so we are struggling to comprehend the animal. We bought back a few - biggest about 80mm long from a clay/silt deposit. Cheers in advance...
