Back to the creek, stopped by the spot the kiddies had been working. Although nothing last time, gave it a try. Breezy, but not the sticky hot weather we should have, and the birds and frogs were alive (was almost over-run by a turkey who exploded into the air over top of me.) Almost immediately I found a big mako. Excepting a small chip near the root, it was in great condition (though hard to scan?) About 6 cm, almost 2 1/2 inches along the longest side. Not much of a yield, but I dont find many "big" teeth, so was happy.
Also found several non-serrated heavy small triangular teeth, some of which are for sure mako teeth. Most missing roots, per usual:
