As we're all taught, you can (usually) only directly date the age of a rock if it cooled from lava. But here, scientists have dated dinosaur eggs, using uranium-lead ratios in the calcite. Hugely exciting, maybe groundbreaking. My take @science.org www.science.org/content/arti...
science.org
Scientists directly date dino eggshells for the first time
The new findings narrow age estimates for the clutch of eggs—and may help identify which species laid them

The posterior skull, partial mandible, left flipper, and much of the vertebral column and ribcage are preserved.The skull and mandible of Megabalaena. The skull is quite wide, like modern right whales, and the lower jaw is very large, and must have been about three meters long. Steepness of the braincase indicates the rostrum would have been arched like modern rights and bowheads.
