Description: These could be carnivores or herbivores. sometimes it's easy to tell by looking at the bone porosity. meat eaters normally had more porous bones. two theories exist for this.
1. Is that it made the predators lighter and therefore faster to catch up with and take down prey.
2. it allowed the predators to hyperventilate right before taking down prey, bringing in oxygen directly to their bone marrow for added bursts of energy.
These bones are mostly black and brown, unlike USA's that have colours.
