Cool fossils!.   I think we both know how lucky we are to live in a country that is abound with fossils...

Here's a few I've stumbled across ...

The top left and sausage shaped pieces are coral which I found 150 km inland !

Some nice pieces there. Where you used to live, Nijar, there is an old dormant volcano that is constantly disgorging garnets. After a rain the ground is covered with them. We collect them in there hundreds and have a deal with a jewellery manufacturer in Germany who purchases those that can be faceted and polished,

FOSSILS: (are these reasonably correct attributes?)

My wife dug these out on her recent Utah trip with one of our Granddaughters...

(please excuse the crappy photos shot on my phone)

This is a pair of fossil ferns from the Llewellen formation in St. Clair, PA (300 million years old). I wouldn't call these especially rare, but the parcel of land in St. Clair where these fossils used to be found everywhere is no longer open to the public. I bought these because I loved the contrast between the white fossils and the black shale. They are each about 10-1/2 inches wide.

They are stunning, like the cameo on a proof coin.

These are fossilised sea urchins (echinoidea). Here in Spain they are called Herizos de mar, or, hedgehogs of the sea as urchin is an old world name for hedgehog, taken from old  French herichun  and Latin ericius  both meaning hedgehog.

I have some cool fossils that I bought, but of course it's much more fun when you find them yourself, so I'll show those instead.  First off is a bunch of shark teeth from a famous site called Big Brook in central New Jersey.  The sharks and other marine fossils found here are from the end of the Cretaceous period (c.66 million years old).  This is a RIker mount display case of just shark teeth from the site (I've also found various fish fossils, a few types of shells, and even a couple of mosasaur teeth (an extinct group of swimming reptiles- think crocodiles with flippers instead of legs).  While these are easily recognizable as sharks, the particular species are all extinct:

Next is a site closer to where I live now, the Calvert Cliffs of the western shore of the Chesapeake Bay in Maryland.  This site is of Miocene age (c. 14 million years old).  Many of the shark teeth and other fossils are from species that still exist.  In the group below, the sharks include the extinct Snaggletooth shark, an extinct Mako relative, and an extinct Tiger, while extant (still-living) species include Tiger, Sand Tiger, Bull, Hammerhead, Six-gill, and Angel sharks.  The bottom rows also include sting ray, drumfish, barracuda, and porpoise.

There are no fossils found in or immediately around Baltimore City (no exposures of fossil-bearing rocks), but there are a few minerals around.  My local city park has lots of mica that weathers out after storms.  Here's a few pieces I've found (they are about 2 inches [5 cm] long):

An impressive display

Agate is something that fits well on this site. Ornamentally, it was used for the seal stones of Ancient Greek warriors and is part of Minoan history. Before that, to the 3rd Millennium BCE, polished agate was used  as jewellery in the Indus Valley Civilisation.

All are from manufacturing processes r R&D that I've worked on.  Primarily high tech ceramic materials, SiC, various stabilized and partially stabilized ZrO2 minerals, a borosilicate based glass ceramic, and a couple copper trees from a plating process.They may look natural but aren't.
