First of their kind scans of preserved infant woolly mammoths have made the insight into the early stages of development for the 40,000 year-old prehistoric animals less fuzzy.

According to a report published July 8 in the Journal of Paleontology, researchers performed a full body CT scan of two mammoth newborns, named Lyuba and Khroma, who died at the ages of 1 and 2 months respectively. The skeletal structures of the infants, which researchers consider to be the most well-preserved baby mammoth specimens found to date, gave the scientists the chance to document the various changes that occurred to the body as the ancient pachyderms grew. They also helped determine whether the mammoth gestation periods may have been shorter than that of modern elephants.

It's everyone's favorite question when it comes to record-setting birds: which is the fastest? The peregrine falcon has taken the trophy for fastest, reaching an incredible 242 mph on a high-speed dive. The much larger golden eagle is not far behind with a maximum dive speed of 200 mph. However, this is on a dive, when gravity is certainly helping the bird reach such mind-blowing speeds.
