Over two decades, Franco has illustrated more than 50 books on dinosaurs and prehistoric mammals for major publishers worldwide. His piece “T. rex couple vs. Dakotaraptor pack” won the 2016 John J. Lanzendorf-National Geographic PaleoArt Prize. He compares the scene to lions defending a kill from hyenas, highlighting the possible social dynamics between top predators and opportunistic rivals.

We bring back our fan-favorite segment: Dinosaurs on Trial! Patrons submitted dinosaur “crimes,” and we argue the cases like whether or not compsognathids are misidentified juvenile theropods. Plus a new ornithomimid from Uzbekistan named Dzharacursor.

Dinosaur of the day Nurosaurus, an informally named sauropod with a stress fracture in its toe.

In dinosaur news this week:

• There’s a new ornithomimid dinosaur, Dzharacursor bissektensis, that may contain medullary bone

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?
