Hunger governs every hour. By day, by night, and through the afternoon, want holds sway. The trio of infant Tyrannosaurus emits eager grunts that can feel relentless, the only quiet coming in brief intervals when their sharp little jaws clamp around scraps of meat dropped into their increasingly odorous nest, or when weariness from pleading drags them to sleep. Whenever the three are awake and empty-handed, their cries resume.
The youngsters remain so tiny that their mother T. rex could drag an entire bloated Torosaurus carcass over to them and they would peck at the ragged edges for days, never exhausting the feast laid before them. The little ones could sate themselves on rotting meat long before finishing the spread, yet such a simple path to full bellies would hardly ease the burden of this busy, fluffy family. The mother T. rex has a appetite wider than any endless pit, and pursuing prey is hard enough—let alone delivering meaty, fatty sustenance. For the moment, she must endure so her offspring have a chance to carve out their own niche in this humid Cretaceous landscape. She can sometimes return with a haunch or broken ribs bound by slender bands of muscle and tissue, but not every meal is lavish.
Protein-rich milk would make things a little easier and require fewer blood-spattered errands, but mother T. rex has no milk to give.
Whatever nourishment the little ones consume, it must come from another creature. The dinosaurs’ digestive systems cannot break down vegetation into anything but an uncomfortable gas bloating. The hatchlings require fat and protein, blood and guts—the raw sustenance that has allowed carnivorous dinosaurs to spread across the planet for roughly 165 million years. Protein-rich milk would ease the burden and cut down the blood-soaked foraging, but mother T. rex has no milk to offer.
Milk is produced by a variety of beings. The chattering and barking mammals that scamper through these woodlands rely on the pale fluid to fuel rapid growth, giving mammal pups the materials to begin turning the pliant cartilage of their skeletons into sturdier bone. Some insects too manufacture their own form of milk—protein-laden secretions that ooze from tiny openings on their bodies, supplying their wriggling offspring with a head start. Even certain birds have managed the trick, disgorging a viscous liquid from their throats to feed their chicks as the hungry nestlings demand more meals. Non-avian dinosaurs, however, never developed this capability.
Suckling is out of the question for T. rex, anyway. Across their lineage, Snaggletooth and her siblings have inherited jaws that will shift and strengthen to deliver bone-cracking bites. The creatures have not evolved the combination of bones and muscles necessary to purse their mouths and draw milk from their mother or drink it in the usual way. Biting and breaking become far more crucial for Snaggletooth and her kin. The push to become adept predators has also produced a precocial youth. The earlier the hatchlings learn to stalk, ambush, and dispatch prey, the better their chances of surviving in these forests and swamps. The nest remains warm, safe, and under mother’s protection for now, but every passing moment nudges Snaggletooth closer to the day she must leave her mother’s side and thrive in a world filled with much larger beings—including other T. rex—that could wound or kill her. Every ounce of practice matters while sheltered in the nest.
Sanguine offerings brought home by mom do help, certainly. Yet tyrannosaurs have not prospered in these damp woodlands of prehistoric Utah simply by exchanging gifts. Snaggletooth and her siblings will need to locate prey, seize it, consume it, and make the most of any juicy, decayed bonuses scattered across the landscape. Each chance to lunge at one another, swat at gnats, and pull fragments of meat from bone matters. Unaware to them, they are training for the routines they will perform for the rest of their lives. T. rex remains in a perpetual audition for survival, and at this moment the youngsters must dodge becoming prey while learning to hunt for themselves.
Fortunately for Snaggletooth, the nest is a mess. The trampled sticks and conifer needles forming the cozy hollow in the earth have absorbed the gunk from discarded eggshells, hatchling waste, blood and fluids from the meaty meals mom has regurgitated for the youngsters, and other pungent substances produced by living things. The nest is heavy with carnivore scents, a blend of their own strong musk and the stench of blood and decay. No wonder flies are almost always buzzing around the depression, not to mention crunchy beetles and spiders that prey on other invertebrates.
T. rex is in a constant audition for survival, and in this moment the little ones have to avoid becoming prey while learning how to hunt for themselves.
A pudgy fly gleaming in metallic blue becomes the latest morsel to catch Snag’s eye. Her ears pick up lower frequencies, like her mother’s calls, so she misses the persistent hum as the fly darts about the nest, slapping its disk-shaped mouth onto scraps of meat and urea-soaked patches of nest litter each time it lands among the trodden debris, yet the insect’s erratic movement has captured the fluffy little tyrannosaur’s gaze. Each time the restless bug pauses, Snaggletooth steadies for a strike, only to be thwarted as the fatty snack zips to another spot in the nest. The insect seems to taunt her. She must seize it.
Flattening her clawed toes on the nest floor, Snaggletooth crouches low and erupts toward the fly. The moment she moves, the insect darts away, weaving a frantic path through the air. Evading danger is a bit easier when you’re much smaller and swifter than your pursuers. Snaggletooth snaps at the air with her tiny jaws, missing the fly’s trajectory as it appears to vanish. Other potential meals slide and reel across the nest, but Snaggletooth fixates on the one she intends to swallow. She notes that the fly has returned to the same patch of offal.
Snaggletooth watches, tilting her head slightly while her body remains still. Tensed. Jaws clenched tightly, ready to snap open at any moment. She simply needs the right instant. The strike isn’t so much about pinpoint accuracy as enclosing a space—ideally one that the fly inhabits when her jaws slam shut. It’s training for future ambushes against juvenile hadrosaurs and for snatching hatchling Torosaurus, the techniques of an ambush predator. She will fail more times than she succeeds. All the more reason to practice, to learn movement patterns, to spot when a meal becomes vulnerable, and to prepare for that first decisive bite.
