During the Cretaceous Period, two of the most feared predators were the massive tyrannosaurus rex and the much smaller but speedy velociraptor. The T. rex stood 20 feet tall, weighed seven tons, and had a jaw powerful enough to crush bones. In contrast, the velociraptor was just three feet tall, weighed 35 pounds, and relied on its speed and a deadly retractable toe claw to hunt. Both had forward-facing eyes for tracking prey, but they never encountered each other, as raptors went extinct millions of years before T. rex appeared.

You’re mostly right that Velociraptor and Tyrannosaurus rex didn’t meet — but the last sentence is a bit misleading.
Corrections and clarifications:
- Velociraptor (the species V. mongoliensis) lived in Asia about 75–71 million years ago. T. rex lived in North America about 68–66 million years ago. That means Velociraptor and T. rex were separated both in time (a few million years) and in place, so they didn’t encounter one another.
- However, “raptors” (the dromaeosaurid group) did not all go extinct long before T. rex appeared. Several dromaeosaurids persisted to the end of the Cretaceous and some (for example Dakotaraptor) are known from the same late‑Cretaceous North American formations that also contain T. rex fossils.
- Sizes and traits: T. rex reached lengths up to ~12 m (40 ft), weights typically estimated in the ~5–9 metric ton range, and had an extremely powerful, bone‑crushing bite. Velociraptor was much smaller (~2 m long from nose to tail, about 0.5 m tall at the hip, roughly 15–20 kg or ~35–45 lb), fast and lightly built, and had a large, sickle‑shaped second toe claw held off the ground (often described as “retractable,” though it was a hyperextendable weapon rather than a true retractable claw like a cat’s).
- Both groups had forward‑facing eyes and some degree of binocular vision useful for tracking prey.
If you’d like, I can make a short timeline or map showing their ages and ranges, or compare T. rex with a North American dromaeosaurid that actually coexisted with it.
