By the way, a Cretaceous turtle and Ordovician trilobite were
found in separate drill cores in Florida.
In 1955, the Amerada Petroleum Corporation drilled wildcat well
12 miles northwest of Okeechobee, Florida. A well core from
9,210 feet contained the remains of a Cretaceous aquatic turtle.
The core, which was composed of gray argillaceous dolomite,
was 4 3/ 8 inches in diameter, recovered the anterior or front
end of it. Its skull and hind portions were outside the area of
the core (Olson 1965:4).
Further north, A similar chance recovery from a drill core was
made in Madison County, Florida. In 1944, the Hunt Oil Company
recovered drill core from depth of 4,628 feet. It contained a
Middle Ordovician trilobite (Colpocoryphe exsul) (Olson 1965:4).
The paper that describes and illustrates the Florida trilobite is:
