Vanderbilt University paleontologists are looking into the evolutionary origins of the whistles and squeaks that dolphins and porpoises make - part of the rare echolocation ability that allows them to effectively navigate their dark environment. Modern dolphins and other toothed whales (a group known as odontocetes) use complex sonar frequencies or "echolocation" to communicate with each other, navigate the deep seas, and to hunt their.

Location. North Carolina. Posted February 2, 2012. This is a collection of fossil Dolphin teeth and ear bones that were found in Aurora, NC in the Lee Creek Phosphate mine over the years. Some self collected and some purchased. In the mix of teeth are a couple of teeth that I don't believe are Dolphin.
The ear bone fossil of an ancient toothed whale that lived 26 million years ago has revealed that its ability to echolocate is quite similar to the present day dolphins' sensory capabilities. The team, one of the first in the world to examine the ability's origins, used a small CT scanner to look inside a 30-million-year-old ear bone fossil from a

The evolution of mammalian auditory ossicles was an evolutionary process that resulted in the formation of the bones of the mammalian middle ear. These bones, or ossicles, are a defining characteristic of all mammals. 180-million-year-old giant "sea dragon" fossil discovered in UK 01:04.
