Tiny ‘vampires’: Paleobiologist finds evidence of predation in ancient microbial ecosystems
A paleobiologist has found evidence of predation in ancient microbial ecosystems dating back more than 740 million years. Using a scanning electron microscope to examine minute fossils, Porter found perfectly circular drill holes that may have been formed by an … Continue reading

Earth’s first ecosystems were more complex than previously thought, study finds
Computer simulations have allowed scientists to work out how a puzzling 555-million-year-old organism with no known modern relatives fed, revealing that some of the first large, complex organisms on Earth formed ecosystems that were much more complex than previously thought. … Continue reading

Large, violent animal packs shaped the ecosystems of the Pleistocene epoch
Intense, violent attacks by large packs of some of the world’s biggest carnivores — including extinct lions much larger than those of today, and sabertooth cats — limited the population sizes of mammoths, mastodons and other species, and prevented widespread … Continue reading
