We are, however,  learning more and more about this important phase of their history, in a time known as the Late Triassic some 231-201 million years ago. A new fossil site from this time in Poland – probably not one of the places you’d associate with important fossils – is helping to fill in the blanks. Usually, dinosaur-bearing sites from around this time are known from the southwestern United States and southern South America, so a European locality can potentially tell us quite a bit!
