Despite two centuries of incredible discoveries, an inability to locate fossils means that many secrets about these species will never be found, says David Hone
THE study of dinosaurs has made some amazing strides in the past 20 years. The discovery of numerous fully feathered dinosaurs offers incontrovertible evidence of the evolution of birds from their non-flying ancestors, for instance. We also have fossils that preserve ancient patterns of these long-extinct animals.
We may have some ideas about the colours of a few dinosaurs, but these are only a handful of individuals that may not even be that representative of their species, let alone any others. We have done detailed studies of howcould stand, walk, run and turn, but there is nothing like this even for the other 30 species of tyrannosaurs, let alone other groups.
In short, however bizarre we consider dinosaurs to be now, they almost certainly produced far more interesting and unusual animals on all manner of islands in the Mesozoic Era , but it is incredibly unlikely that we will ever find them. Either the fossils never formed or those islands have been destroyed and are now inaccessible.
