END OF THE DINOSAUR ERA TOPIC FOR LECTURE AT SLU

CANTON -- Brian T. Huber, curator in the department of 
paleontology at the National Museum of Natural History, 
Smithsonian Institution, will speak on "The Deep-Sea Record of 
Asteroid Impact That Ended the Dinosaur Era" at St. Lawrence 
University.
	Huber's talk, the 2000 Susan Caroline Ferguson Lecture, 
will be on Thursday, April 20, at 8 p.m. in Bloomer Auditorium, 
Brown Hall. It is open to the public, free of charge.
	Huber is a curator of foraminifera, single-celled organisms 
that have inhabited the oceans for more than 500 million years. Both 
living and fossil foraminifera come in a variety of shapes and sizes 
and occur in many different marine environments -- from the shoreline 
to the deep sea, and from near the surface to the ocean floor. Their 
abundance, wide distribution, and sensitivity to environmental 
variations make them good indicators of past climate change.
	Huber will discuss items from the museum's collection that 
are evidence of an asteroid's impact on the Earth, and believed to 
be the cause of dinosaurs' extinction.
