The 7 January 2010 Nature podcast has an interview with Per Ahlberg, one of the authors describing some wonderful new old tracks – new to science, but dating from 397 million years ago. They’re fossil tracks of early tetrapods – which is the lineage including amphibians, reptiles, mammals, and bird.
About four and a half minutes in, Ahlberg says:
This is going to be in the textbooks fifty years from now.
And I thought, “Wow. He’s confident.
“I wouldn’t be so sure that textbooks are going to exist in fifty years.”
It will be a shame if we are still relying on “dead tree” compilations of old research to teach students fifty years from now.
A good summary of the tracks and their importance can be found here.
