It's down to just a final, furry 4 potential nicknames for our hypothetical placental ancestor! Vote for the two finalists now.

Opening tomorrow, the special exhibition Whales: Giants of the Deep is co-curated by John J. Flynn, Frick Curator of Fossil Mammals, Division of Paleontology, and Dean of the Richard Gilder Graduate School. We recently spoke with Dr. Flynn about the exhibition’s many highlights, his fieldwork in South America, and his sightings of whales in the wild.

A whale of a tale! In a video, get the inside view from Museum curators about our newest exhibition, Whales: Giants of the Deep, which opens Saturday, March 23, 2013.

A video series on amnh.tv delves into the topic of dinosaurs, which arose some 230 million years ago and thrived until large dinosaurs became extinct about 65 million years ago. How did dinosaurs reproduce? A video explains.

Okay, just 8 possible nicknames left. Does our hypothetical common placental ancestor look more like a Placentor or a Mancestor? Nova or Hypotheshrew? Make your vote today for a final, furry 4!
