Fossil Dinosaur Eggs

Today, Wādī al-Ḥītān (the Valley of Whales) is in the middle of western egyptian desert, but once it was covered by the sea and was the home of this "crocodilesque" ancestor of modern whales, the Basilosaurus: a 49/59 feet long predator with 44 sharp, harpoon-like teeth. When the sea became to dry, whales were simply unable to escape.

This fossil specimen of a Jewel Beetle (family Buprestidae), found in Messel, Germany, still retains its iridescence. This is caused by a large number of microscopic reflectors still preserved in this prehistoric insect.

Giant insects disappeared thanks to falling oxygen levels and agile birds. "The largest wings of any living insect belong to the Queen Alexandra birdwing butterfly and the atlas moth. They can span 10 to 12 inches across. But even these giants are puny compared to the insects of prehistory. Meganeura, for example, was a dragonfly that lived 300 million years ago and each of its wings was the length of my arm. Why do such behemoths no longer exist?"

Three-day-old embryos of red-eyed treefrog species Agalychnis callidryas. The embryos have external gills that protrude toward the surface of their eggs, where oxygen is most concentrated. This adaptation allows for high metabolic rates and accelerated development. Karen M. Warkentin
