A research of frogs from the late Late Oligocene interval in Florida discovered that frogs of the genus Eleutherodactylus dispersed from the Caribbean into North America over water. The researchers say the fossils of Eleutherodactylus from this era signify the most important class of frogs in Florida.
The paper notes that the institution of those species in Florida have been influenced by modifications in local weather and ecology and these modifications labored on differing geographic scales. The researchers in contrast Eleutherodactylus fossil specimens from the Brooksville and Reside Oak localities in Florida, each that are of the Late Oligocene period. They recognized 174 Eleutherodactylus frog fossils collected in Brooksville 1994, and three frog ilia, or hip bones that have been collected in Reside Oak again in 1974.

They in contrast these fossils with that of bones of fossils and extant frog genera from North America and the Caribbean. Three dimensional reconstructions based mostly on CT-scans in addition to specimens preserved in fluids have been examined to estimate measurements comparable to physique measurement and size. The fossils studied within the paper vary in physique measurement from 16.8 to 29.8 snout urostyle size.

The researchers say that the fossil report in Florida from the Oligocene interval confirms that the North American anuran fauna of the Cenozoic period originated in North America or got here to the continent through Asia, South America, or, as detailed on this research, the Caribbean over water. They be aware that Florida retains probably the most full fossil report of anurans from North America that extends from the Oligocene to the Pleistocene eras.
