Busted All Dinosaurs Went Extinct an amazing fossil in Germany It was Most people think all dinosaurs went extinct 65 million years ago It is true that many of the best a small raven sized dinosaur It had known dinosaurs died out in the wings and feathers Paleontologists named it Archaeopteryx from the Greek words for ancient wing distant past Tyrannosaurus rex Velociraptor and Triceratops are long gone But some dinosaurs In the late twentieth and survived Their descendants continued to evolve Today we call early twenty first centuries paleontologists made many more discoveries They found more Archaeopteryx fossils They also found other them birds Scientists found the first connection between birdlike dinosaurs dinosaurs and birds in Archaeopteryx was the size of a raven and had feathers The more they learned the stronger 1861 They uncovered
the connection between dinosaurs These Hadrosaurus and other dinosaur eggs are similar to bird eggs and birds became Today most experts agree that birds are modern dinosaurs Many pieces of evidence lead to this conclusion Some types of dinosaurs have bones shaped like bird bones Dinosaurs and birds have similar eggs too Dinosaur fossils have even been found in the same resting positions birds use today Scientists now believe many dinosaurs had 150 million Number of years ago Archaeopteryx lived feathers All this evidence points to an amazing conclusion Not all dinosaurs went extinct Instead many of them still soar in the Archaeopteryx was one of the first birdlike dinosaurs discovered Birds and dinosaurs share many traits Paleontologists now believe birds are the descendants of dinosaurs sky
Busted Brontosaurus is the same as Apatosaurus In 1879 American paleontologist Othniel Charles Marsh was hunting for dinosaur bones He uncovered In 1903 paleontologist Elmer Riggs argued that Brontosaurus was not new He compared it with another a gigantic sauropod in Wyoming sauropod Apatosaurus He believed Sauropods had very long necks with the Brontosaurus fossil was just small heads stout legs and skinny a younger Apatosaurus Other tails Marsh called the new sauropod scientists agreed For more than a Brontosaurus The name means century Brontosaurus did not exist thunder lizard Marsh's fossil was believed to be a young Apatosaurus 70 Average length in feet 21 m of Apatosaurus THE BONE WARS Marsh was one of the most famous scientists of his time Brontosaurus fossils were found and named in 1879 He competed with American paleontologist Edwin Drinker Cope to find the best fossils Their rivalry became known as the Bone Wars The men In 1903 scientists agreed Brontosaurus was simply a young Apatosaurus New research published in 2015 suggested Brontosaurus was its own sauropod species after al became bitter enemies They spent large sums of money to be the first to make new dinosaur
a Marsh In 2015 European other parts top center with the paleontologists The research armed field crew brought Brontosaurus took more than that accompanied back into the spotlight five years The him on digs They published a study team traveled of 81 separate sauropod across the world fossils They looked at neck studying sauropods bones shoulders and many They wanted to learn how sauropods differ from one THINK ABOUT IT another They discovered Marsh's Brontosaurus had enough unique features to be considered its own dinosaur after all Why does it matter what scientists call a particular type of dinosaur How might names and classifications be useful when studying
