Three Floating Frame Display Cases With Fossil Shark Teeth.
|
I like to find nice ways to display finds. Fossils can be difficult to display, but I recently got these display frames. I put shark teeth in them so you can see how they look, but you can put other things in them as well, as long as they are not too bulky or heavy.
The frames are hinged and open up so you can put whatever you want in them. There are two Mylar sheets that hold the items in place when the frames are closed. And they come with bottoms that allow you to hold the frames as shown or like a square instead of the diamond-like shape shown in my photo.
They come in both white and black and four different sizes. They are not expensive. They are known as floating frame display cases. I'm sure you will be able to find them online.

Yesterday I referred to the Florida Environmental Protection Agency report on Hurricanes Frances and Jeanne. One of the things I posted was some illustrations of various levels of beach erosion. I'll take a closer look at each of those today.
First, here is what they called minor beach erosion.
Only the front of the beach close to the water line is eroded. Of course, front beach erosion can be either very slight or more significant and it can extend far back onto the flat beach. When the beach has already been eroded, either recently or over the decades, minor erosion can be enough to expose old items, but when the beach has been building over the years like it has at some Treasure Coast beaches, it will take a lot of erosion to expose older items.
Here is what they call "Condition II," which involves both beach front and dune erosion
That of course means the water had to be back to the dunes. Dune erosion can expose old items if the dunes are not protected by a lot of more recent sand such as the renourishment sand at beaches such as Wabasso, Seagrape, and Turtle Trails. Anytime dune erosion reaches the old sand though, old items can wash down onto the beach.
In their example of "moderate dune erosion" they show erosion extending from the front beach, through the mid or flat beach all the way back to and including the dunes.
What they call major beach erosion, involves removal of a lot of the dunes uas well as some of the mid beach. That is the kind of thing that was caused by Frances and Jeanne and the Thanksgiving Storm of 1984.
This example shows how the sand was washed down into the water and extending the beach.
The report was very much interested in property damage, so they were very much interested in what happened to the dunes or back beach, which is where most of the buildings are.
Being more interested in treasure, I would have also included at least one additional beach profile to show the case in which the mid or flat beach was significantly eroded without the dunes being eroded. That does happen and can, of course, expose treasure. It happened back in February and March of 2020 on a couple of occasions.
The also gave another example, wing the entire removal of the dunes. I'll label it as example V for now.
That example leaves the mid beach nearly unchanged but extends the front beach into the water.
On the Treasure Coast if the water got high enough to remove the dunes, that could result in the dune sand being washed back into the lagoon instead of out into the ocean. It could also result in a new inlet being created.
I don't remember which year it was now, but one year the beach was eroded almost back to blind creek. It was only yards from being opened.

Two Tropical Storms Now.

It looks like neither Josephine or Kyle, both of which are tropical storms, will do much for us.
Happy hunting,
