6/30/20 Report - Calm Surf and Sandy Beaches. Treasure Coast Fossils. Fishing Artifacts.

Typical Sandy Treasure Coast Beach.


The Treasure Coast beaches have been accumulating sand for weeks now.  In the photo you can see where the waves are crashing on a sand bar and then washing sand in, during high tide, up on the beach.

Waves Breaking on Bar

If there is a dip inside the bar, the waves will break on the bar and then disappear if the dip is deep enough.  Where there is less of a dip, the waves will continue in.  You can easily look out and see where the dips are.  


Waves Breaking on Sand Bar.

The dip shown in the above photo had a lot of loose sand and shells in it.  The water was clear and you could see what look like waves of sand on the bottom.  It was far from washed down to bedrock.

Recently I posted a photo of a fossil snake vertebra that I found on a Treasure Coast beach.

Here is an article discussing the evidence that men ate snakes long ago.  Notice the reptile vertebra  pictured in the article (below).

Here is another small fossil vertebra found on a Treasure Coast beach.  It is in great shape and is very different than the snake vert.  I don't have any idea what type of animal it might have come from.

If anyone can tell me the animal, I'd love to know.  It doesn't look like the fish verts that I'm familiar with.

Here are a couple stone-age fish hooks found at an inland site that was once a lagoon.  Between 1932 and 2020 the land was drained.  You can see that the fishhook that was excavated before the land was drained is in much better condition than the one excavated from the drier earth.

As they mentioned on the Dino Hunters TV show, bones have to have the right conditions to fossilize.  After an organism's soft tissues decay in sediment, the bones are left behind. Water seeps into the remains, and minerals dissolved in the water seep into the spaces within the remains, where they form crystals.

An area of low pressure off North Carolina has a small chance of developing into a cyclone in the next 48 hours, but it is expected to head northeast.

The surf remains small on the Treasure Coast.

Happy hunting,
