In dinosaur news this week:

For our Dinosaurs on Trial segment, patrons submitted dinosaur “crimes,” and we argue the cases:

• Did Ankylosaurus cruelly attack a mother T. rex in Walking With Dinosaurs?
• Are compsognathids just mislabeled juvenile theropods?
• Did T. rex throw the fight against Spinosaurus in Jurassic Park 3?
• Did T. rex really hunt with F-14s?
• Was Oviraptor a misunderstood parent or an egg thief?
