Guest Posted September 30, 2010 Share Posted September 30, 2010 Paleontologists have unearthed the first extinct penguin with preserved evidence of scales and feathers. The 36-million-year-old fossil from Peru shows the new giant penguin's feathers were reddish brown and gray, distinct from the black tuxedoed look of living penguins. The fossil shows the flipper and feather shapes that make penguins such powerful swimmers evolved early, while the color patterning of living penguins is likely a much more recent innovation.

SRC Member allantang Posted October 2, 2010 SRC Member Share Posted October 2, 2010 carbon dating.. 1/2 life.... carbon dating hor... has 1 too many variables.. any one of the following changes... it will make the whole reading totally inaccurate. 1. the rate at which carbon-14 decays into nitrogen-14 has not changed throughout the unobservable past 2. the ratio of carbon-12 to carbon-14 was in the environment in which the specimen lived during its lifetime 3. there has not been any contamination in the specimen which we are attempting to date. the first 2 points need someone to live 36 million years to make sure it don't change.. i have yet to find out who.. haha Quote Link to comment Share on other sites More sharing options...
