Where have all the makos gone

Two weeks ago we were heading down to the beach talking about how we havn't found many makos this spring ,well not many i couild put in the case.The tide overnight must have fallen fast leaving the beach covered with shell and fossils. With the beach to ourselves we split up to try to cover as much as possible before someone else wandered along. After four passes down the beach we were still picking up teeth. We covered are lack of makos with two 1 7/8 makos ,six between 1 1/4 to 1 1/2 and over 30 small makos .We also found two small megs , a broken 3 inch meg,a nice cow and several good hemis.With most of the easy finds off the beach we started checking the beach boulders and spotted a large rib sticking out between two car sized blocks.The huge block must have fallen and split open along the length of the rib when it crashed into the water.It had left the rib intact in one block and the inprint in the block next to it.We spent the next 30 min prying it loose and packing the four foot bone in the boat in as few pieces as possible.This ate up a good chunk of time and we could now see a few people walking down the beach. So I headed off to take one last look before we were overrun.Stepping over a fallen tree just 20 feet short of first person I spot a root in the sand .The best find of the day a 1 1/2 giant thresher. With the tooth in hand we pushed off not wanting to anger the fossil gods by taking too much.
