Dieting dinosaurs
Many of the biggest dinosaurs, such as some of the long-necked sauropods like
Brachiosaurus, Titanosaurus, and Apatosaurus, would have eaten colossal amounts
of vegetation.
So why do we find such a conspicuous absence of plants in rocks containing
dinosaur fossils? Take for example the Morrison Formation in Montana, USA. Even
though this Formation has yielded many dinosaur fossils, there is a startling
scarcity of vegetation preserved. This phenomenon of ‘missing vegetation’
doesn’t just apply to dinosaurs. The Coconino Sandstone in the Grand Canyon has
many animal track-ways, but it is almost devoid of plants. These rocks tell us
something profound about earth history. They suggest that these deposits are not
ecosystems buried over eons of time, otherwise we’d find more evidence of the
plants that the animals ate. Instead, the evidence fits nicely with the biblical
model of earth history, whereby these animals were transported and buried
catastrophically, during Noah’s flood.
