News from this newspaper When it comes to scientific accuracy, many dinosaur toys may be far behind. Paul Olsen, a dinosaur expert at Columbia University in the United States, said on his blog that one of the main shortcomings of this toy is that the animal made of plastic lacks feathers, causing the dinosaurs to be completely exposed. In addition, many toys will make similar screams, but the range of real dinosaurs may be very wide. However, he said that comparing toys with books and pictures that accurately depict dinosaurs known to scientists would be a good learning opportunity. But for those children who love this prehistoric animal, the lack of feathers will not affect their fun from toys.
