Hurricane Ike leaves mammoth tooth
in scientist's backyard

Discovery: Paleotologist Jim Westgate holds a fossil tooth of a mammoth that he found in Texas in the debris from Hurricane Ike
A paleontologist whose beachfront home in Texas was destroyed during Hurricane Ike has found a mammoth's tooth in the debris.
Scientists Dorothy Sisk and Jim Westgate discovered the football-sized fossil in Sisk's front yard in Caplen on the devastated Bolivar Peninsula.
Westgate believes the fossil, which looks like a series of boot soles or slices of bread wedged together, is from a Columbian mammoth common in North America until around 10,000 years ago.When Lamar University professor Dorothy Sisk returned to her devastated beachfront home, she searched through what few belongings were strewn about - a bowl, a broken vase, a scrap of fabric.
“She picked up a couple things,” said LU colleague Jim Westgate, who had volunteered to drive her to the site in his pickup.
All that remained of the home were scraps of concrete and splintered pilings.
“It was while we were looking at the house, or at least what was left of the foundation, that I saw it lying there with lots of shell debris in what had been the front yard,” Westgate said.
Westgate, a trained paleontologist and a research associate with the Vertebrate Paleontology Laboratory at the University of Texas Memorial Museum, recognized the fossil tooth of a mammoth.
“This is the first one I’ve found in 19 years,” Westgate said. “People bring in pieces and parts from the beach for me to identify, and I haven’t seen one in this good a condition.”
The 6 lb (2.7 kg) tooth, which resembles a series of boot soles or slices of bread wedged together, is most probably that of the Columbian Mammoth, a species common to North America until around 10,000 years ago, Westgate said.
At that time, mammoths and mastodons, which are ancestors of the modern elephant, roamed the continent in large numbers.
Their fossil teeth are easily distinguished from one another by the grinding surface, Westgate said.
Mastodon teeth are bumpy, and resemble a series of steep mountains and deep valleys, whereas mammoth teeth are flatter and well-suited to grinding.
It is believed that mastodons ate leaves, bark and fruits, whereas mammoths were predominately grazers.
Like modern elephants, mammoths grew a total of six sets of teeth during their lifetime, ejecting worn teeth “like a shotgun, loading a newly formed tooth in its place,” Westgate said.
The discovered tooth is unworn, so it was either newly erupted or a “tooth in waiting” when the animal died, Westgate said.
It is expected that the tooth will be sent to the Texas Memorial Museum in Austin.
More than 1 million people fled the Texas coast because of Hurricane Ike.
