Winter bugs called snow fleas are born in icy waters and feed on algae that grows on snow. Spring-tails are also called snow fleas and they leap around on snow banks. They eat the sap which oozes from trees. Spring-tails look very similar to fossils of 300 million years ago!
Prehistoric Mouse "a little smart cookie"
Prehistoric Mouse "a little smart cookie" A mouse-like animal that lived some 195 million
years ago had a body so tiny that it could have curled up on a
loonie. This "Hadrocodium wui" was the smallest animal of the
dinosaur age - weighing just 2 grams, like a paper clip, but had a
brain that was much bigger compared to other mammals. The name
Hadrocodium wui means larger and full head. Researchers say that it
holds an important position in the evolution of mammals and could
be the ancestor to all mammals, including humans. Hadrocodium wui
probably lived on bugs and worms, catching them with long, canine
-like teeth, and most likely had to eat the whole time it was awake
because it had such a fast metabolism. It also is suggested that it
hid during the day, and adapted a nighttime existence to avoid the
dinosaurs. FRIDAY, MAY 25, 2001
