Great Whites, Megalodon and Cretalamna, Oh My!
Research on the Origins and Paleobiology of Lamniform Sharks
Dr. Dana Ehret
Assistant Curator of Natural History, New Jersey State Museum, Trenton New Jersey
& Former Curator of Paleontology, Alabama Museum of Natural History, Tuscaloosa, AL
Sunday, February 18, 2018 2:00 P.M. Room 319
American Museum of Natural History New York City
The evolution of Great White and Megatoothed sharks has had a complicated relationship over the past 175 years. The discovery of an articulated set of White shark jaws from the Miocene of Peru in 1988 by Dr. Gordon Hubbell and its description by Dana Ehret in 2012 shed light on the evolutionary distinctions between great whites and the megatoothed sharks. Adding to that, the discovery of a new species of Cretalamna from Alabama has further emphasized the different lineages of the megatoothed sharks and the lamnids (great white and makos). Dana will discuss his work on fossil great whites and megatoothed sharks in Peru, Panama and Alabama. In addition to his descriptions of two new species of fossil sharks, Dana will also discuss his work on their paleobiology. Using vertebral centra and evidence of feeding, we are beginning to flesh out how the massive 50 foot Megalodon might have lived and how white sharks interacted with them.
N.Y.P.S. MEETING DATES FOR THE YEAR
