dinasaurs lived in north america , in africa and in europe. during this time the land in north america was under a large shallow sea.many dinasaurs lived in water which helped to hold up their great weight
the early dinasaurs walked on two feet and they ate meat .the later dinasaurs were larger ,walked on four feet and some of them ate plants only
BUT WHY DINASAURS DIED OUT? NOBODY KNOWS FOR SURE
PROBABLY A CHANGE IN WEATHER MADE SERIOUS PROBLEM FOR THEM

the last word "THEM" refers to(dinasaurs - late dinasaurs )
