“That's a combination unlike any on the arctic tundra today, says Charles E. Schweger, a paleoecologist at the University of Alberta in Edmonton.”

“He and a paleoecologist at Monash University were the lead authors of the study.”

“Although some marine fossils more than 500 million years old sport holes, many paleontologists have been hesitant to say these are signs of predators, says a paleoecologist.”

“In time, he became fascinated by issues of taphonomy and paleoecology and read extensively on these subjects.”

“Those studies could, in turn, facilitate additional investigations in paleoclimatology, evolutionary studies, paleoecology, and bioenergetics.”

“Percentages can be misleading, however-only three times since 1926 have more than 10 publications dealt with stromatoporoid paleoecology.”
