Ancient skull found in Ethiopia
(Mar 28, 2006)
Fossil hunters in Ethiopia have unearthed an ancient skull which
they say could be a "missing link" between Homo erectus and modern
people. The cranium was found in two pieces and is believed by
its discoverers to be between 500,000 and 250,000 years old. The
project's director, Dr Sileshi Semaw, said the fossilised specimen
came from "a very significant time" in human evolutionary history.
It was found at Gawis in Ethiopia's north-eastern Afar region.

Streeeetch! Long-neck dinosaur sets new
standard
(Mar 21, 2006)
Scientists have identified a new dinosaur species that had one
of the longest necks relative to body length ever measured. A
typical neck bone in this creature was about the size of two loaves
of bread. The species, Erketu ellisoni, belongs to the group of
massive four-legged herbivorous dinosaurs called Sauropoda, the
largest land animals ever to walk on Earth. This giant group also
includes Brachiosaurus, Diplodocus, and the largest of them all,
the 120-foot long Argentinasaurus.

Baby Triceratops skull suggests reasons
for horns
(Mar 9, 2006)
A baby Triceratops skull suggests the impressive horns of the
beast were for more than just attracting a mate. The three-horned
Triceratops dinosaur weighed up to 10 tons and had one of the
largest skulls of any land animal on the planet. Now the smallest
skull of the species suggests what the horns were for. "The baby
Triceratops confirmed our argument that the horns and frill of
the skull likely had another function other than sexual display
or competition with rivals, which people have often argued, and
allows us to propose that they were just as important for species
recognition and visual communication in these animals," said paleontologist
Mark Goodwin at the University of California at Berkeley.

'Jurassic beaver' found in China
(Feb 28, 2006)
The discovery of a beaver-like fossil that lived when the dinosaurs
ruled the Earth could challenge some currently accepted ideas
on mammal evolution. Castorocauda lutrasimilis, which was unearthed
in China, is a species previously unknown to science. It dates
back to 164 million years ago, a time when mammals were thought
to be primitive creatures confined to land. But this animal was
adapted to life in water, meaning scientists may now have to rethink
their theories.
