Which bird is the closest to dinosaurs?
Which bird is the closest to dinosaurs? Based on genetics and on the fossil record, there’s general agreement that the most primitive groups of birds today are several families of flightless ground-dwellers—ostriches, emus, cassowaries, rheas, kiwis—plus the tinamous, which can fly, but not very well.
Whats the heaviest animal that can fly?
The largest so far discovered is Quetzalcoatlus northropi, which may have weighed more than 200kg with a wingspan of 11 metres. That’s as wide as a Cessna 172 aeroplane!
Where is T-Rex found?
Paleontologists have found most T. rex fossils in the Northwest, in states such as Montana and South Dakota. T. rex fossils have also been found in Alberta, Canada.
How long did T. rex live for?
These studies, done in conjunction with paleontologists at AMNH, document that that Tyrannosaurus, which attained a weight of more than 10,000 pounds as an adult, reached sexual maturity at about 20 years of age and lived for up to 28 years.
