Even though the tide sucks and it was difficult to get up early with dark cloudy skies, it is WARM (though the water lags behind), so I had to get out. The tide lines of shells had been spread out more evenly on the beach and I hoped to find stuff there. But first I walked the incoming tide with surprisingly little to show for it (three sand shark, one decent tiger shark and three shrimp coprolite burrows (still drying). Lots of small "whale bone" pieces. Also a flat piece with scales(?) almost painted with enamel, that is flaking off?? (I default always to turtle.) Walking the beaches I was disappointed; possibly the lack of sunshine and the black bits of leaves and wood just overwhelmed my teeth spotting abilities (i'm half blind). I decided to root around where I had found my half of a megalodon a few days ago, wishful thinking, and while no meg I found a nice 2" mako lying out in the open . Don't think it was there a few days ago. Hunted the rough stuff high on the beach hard but nothing else interesting. But the nice weather and mako and shrimp coprolites turned it into a decent two hour trip trip.
After a couple of trips with four or five small teeth and nothing much else, I returned to the beach at low tide after a NW wind storm and found several of these callianassid "burrows". They tend to be cylindrical with a flattened end, solid and heavy for their size, and stay with the last line of shells in the water. heavier I guess. Unlike the shark teeth, which can be almost anywhere on the beach but usually are most obvious in the wash. The burrows (brown, dark gray or black in the water) tend to be darker (mass of coprolites?) on one (bottom?) side. I found the longest (3 1/2") this trip, and although none are "beautiful" the rod-shaped coprolites become more and more obvious as they dry. Need a good north wind on this beach on the south side of the Rapp for these things to show in abundance (teeth often seem to be covered under the same conditions). Tried another beach and my eyes were overwhelmed with small (1-3") rusted pot metal pieces (not many shells) which make it difficult to find anything really interesting; will try again.
