This passage of water was called the Suwannee Straits. [2] A shallow sea grew to cover most of the state during the Paleogene. Clams, echinoderms, and gastropods lived here. [5] Cenozoic limestone formed in such environments is common in Florida and rich in fossils. The oldest fossil-bearing geologic deposits in Florida are of Eocene age. [2]
The largest deposits of rock phosphate in the United States are found in Florida. [1] Most of this is in Bone Valley in central and west-central Florida. [2]Extended systems of underwater caves, sinkholes and springs are found throughout the state and supply most of the water used by residents.
The subsequent rise in sea level raised the local water table and in more recent times the pond has been fed by groundwater as well as rainfall. In 1984, the pond had a thick layer of peat, with five strata described by the archaeologists who excavated the pond. The peat in the center of the pond was covered by 6 feet (2 m) of water. [3]
In short, the Antikythera Mechanism was a machine designed to predict celestial phenomena according to the sophisticated astronomical theories current in its day, the sole witness to a lost history of brilliant engineering, a conception of pure genius, one of the great wonders of the ancient world—but it didn't really work very well!
The tusk measures about 4 feet (1.2 meters) and weighs 70 pounds (31 kilograms), Lundberg said, and was found at a depth of about 25 feet (7.6 meters) near Venice, Florida.
Volusia County officials estimated it may be a 25- to 30-foot ship, but archaeologists say a lot more is hidden below the sand. The team of experts included the Florida Bureau of Archaeological ...
A paleoshoreline (ancient shoreline) is a shoreline that existed in the geologic past. (Paleo is from an ancient Greek word meaning "old" or "ancient".) [1] Paleoshorelines are driven by changes in sea level over geological time. "Sea level" refers to the average level of a marine water body over a relatively long period of time (years).
