Early Whales Gave Birth on Land
Two newly described fossil whales--a pregnant female and a male of the same species--reveal how primitive whales gave birth and provide new insights into how whales made the transition from land to sea.
The 47.5 million-year-old fossils, discovered in Pakistan in 2000 and 2004, are described in a paper published Feb. 4, 2009, in the online journal PLoS.

Prehistoric Fossil Snake is Largest on Record
Scientists have recovered fossils from a 60-million-year-old South American snake whose length and weight might make today's anacondas seem like garter snakes.
Named Titanoboa cerrejonensis by its discoverers, the size of the snake's vertebrae suggest it weighed 1,140 kilograms (2,500 pounds) and measured 13 meters (42.7 feet) nose to tail tip.
A paper describing the find appears in this week's issue of the journal Nature.

Fossil Steroids Record the Advent of Earliest Known Animals
Using compounds preserved in sedimentary rocks more than 635 million years old, researchers have found some of the earliest evidence for the existence of animals.
Demosponges thrived in the shallow coastal waters of what is now Oman, according to scientist Gordon Love of the University of California at Riverside and colleagues from MIT and other institutions.
They report the results of their research in this week's issue of the journal ...
