A still more remarkable fossil bird called. SKELETON OF ICHTHYORNIS RESTORED the Archicoptcryx has been discovered inEurope in a little earlier page of the earthshistory. First the impression of a featherwas found in the rock, recording as plainlyas possible that the bird was there when therock was soft mud. After a while a verycomplete specimen was discovered, andwonderful to tell,it had a long taillike a lizard, andthe feathers grow-ing on either sideof it.
