The fossil record of Basilosaurus in North America offers valuable information about the geographic range of this species during the late Eocene period, approximately 34 to 35 million years ago. These discoveries indicate that Basilosaurus cetoides inhabited the shallow sea that covered parts of present-day Alabama, Mississippi, and Florida.
The rock formations in these areas, originating from the late Eocene shallow Gulf Coast sea, have proven to be particularly rich in Basilosaurus fossils. Such distribution patterns offer significant opportunities for studying the ecological preferences, migratory behaviors, and evolutionary history of Basilosaurus cetoides within the context of ancient North American marine environments.
Extinction of Basilosaurus and Evolutionary Significance
The extinction of Basilosaurus and its evolutionary significance can be attributed to global cooling and changing ocean circulation, leading to the diversification of modern toothed and baleen whales.
- Climate Change: Global cooling and ocean circulation changes contributed to the extinction of Basilosaurus and most archaic whales around 34 million years ago.
- Diversification of Whales: New currents and deep ocean upwelling favored the diversification of modern toothed and baleen whales, leading to the emergence of new species.
- Evolutionary Implications: The presence of pelves and reduced legs in Basilosaurus isis skeletons suggests a land-mammal ancestry lost in later whales, highlighting the evolutionary significance of Basilosaurus in understanding the history of whale evolution.
The extinction of Basilosaurus marked a crucial turning point in the evolutionary trajectory of whales, impacting the development of modern whale species and providing valuable insights into their ancestral origins.
Characteristics and Size of Basilosaurus Cetoides
Occasionally mistaken for a reptile, Basilosaurus cetoides, the official state fossil of Alabama, was an ancient whale species that reached lengths of 60 to 70 feet during the late Eocene epoch.
