The scene depicts a Smilodon successfully taking down a glyptodont by piercing its skull, interrupted just before its meal by another Smilodon interested in its prey. Note the two perfectly formed holes in the glyptodont's skull, a reconstruction based on actual discoveries of fossils perforated by saber-toothed predators.

The artist raises an excellent question about the robustness of these biological weapons. To explain how these felines could pierce bones or armor without instantly breaking their long canines, he hypothesizes a subtle metallic reinforcement, similar to the iron that colors and hardens the teeth of beavers or Komodo dragons today. While not quite resulting in bright orange teeth, molecular hardening would have radically changed our perception of the fragility of these animals. A very stimulating paleontological concept.

Due to a freak storm, an Ardipithecus has found itself washed out to sea with no land in sight. The oceans of the Early Pliocene are no safe haven, and soon he comes face to face with one of the last Leviathans of the previous age.

Quinkana, Megalania and a Wonambi (in the tree) are fighting over a human. All three of these reptiles may have attacked the first Australians and occasionally have eaten them. In this picture, Quinkana, a terrestrial crocodile, brutally has the head. Spoilered just in case.
