Publishing October 27th, 2026
"Nobody brings dinosaurs and their world to life like Riley Black. Gorgeously written, Tyrant Lizard Queen is reminiscent of animal-centric epics The Black Stallion and Call of the Wild, instantly pulling you into the thrilling inner world of Tyrannosaurus rex. As we follow Snaggletooth the T. rex on her journey from little nestling to fierce adult, we learn fascinating details dinosaur physiology and the Jurassic ecosystem—but most of all, we learn to identify with a creature who has vanished from the Earth, and to appreciate who she really was beyond the myths and monster movies."
—Annalee Newitz, author of Four Lost Cities: A Secret History of the Urban Age and Automatic Noodle
Tyrannosaurus rex is a prehistoric celebrity. Exceeding 40 feet in length and weighing over 9 tons, the largest individuals of this dinosaurian species were intimidating predators capable of crushing bone and consuming more than a hundred pounds of flesh in a bite. But the last of the tyrant dinosaurs had a life beyond ripping and tearing. More than 66 million years ago, T. rex courted each other, nested, watched over their offspring, slept, drank, and explored ancient floodplains inhabited by a fantastic cast of impressive dinosaurs like the huge long-neck Alamosaurus and burly, three-horned Torosaurus. For the first time, the life story of this impressive, sensitive predator is told as if you were there to watch it unfold.
In her latest prehistoric nature walk, bestselling and award-winning author Riley Black follows the life of plucky T. rex Snaggletooth from the time she hatches through her tumultuous adulthood. The prehistoric forest Snag emerges into is full of danger, and yet, as Riley weaves the latest fossil discoveries into the story, the carnivorous dinosaur survives to play, court, fight, sleep, nest, and more as she grows up in Cretaceous North America. She tussles with rival tyrannosaurs, hunts for delectable prey, and finds soft moments of connection in the forest. Even the most die-hard dinosaur fan will come away with a new perspective and appreciation for the Tyrant Lizard Queen.

The Shortest History of the Dinosaurs
“An entrancing primer. . . . Black has a knack for singling out the most surprising and engrossing findings of modern paleontology, bringing the ancient reptiles back to vivid life. The result is an excellent overview of the ever-evolving science on dinosaurs.”—Publishers Weekly
The Shortest History of the Dinosaurs tells the 230-million-year epic of these staggeringly fascinating prehistoric creatures, covering their small beginnings, spectacular golden periods, and stunning evolutionary success—before an unthinkable asteroid event brought everything to a screeching halt. But this history digs deeper, using numerous recent fossil discoveries and fresh understandings of genetics and evolution to show how we’ve gleaned so much about a long-lost world from mere fragments of fossil. Marshaling the evidence, award-winning author Riley Black reveals the startling relationships that dinosaurs shared with one another, the land they lived on, and other animal species.
