Answer
Coprolites, the fossilised faeces studied by Anning, provided valuable insights into prehistoric food chains and ecosystems. By analysing the contents of coprolites, scientists could identify which plants and animals ancient predators consumed, shedding light on predator-prey relationships and dietary habits millions of years ago. Furthermore, the presence of coprolites in different geological formations helped researchers establish stratigraphic sequences and determine the relative ages of different fossil-bearing layers.
