- Tyrannosaurs are the most iconic of all dinosaurs, but what they looked like as babies has been the subject of debate and mystery.
- New research on rare tyrannosaur embryos gives researchers a first glimpse of what big meat-eaters just hatched from their eggs looked like.
- When the dinosaurs first hatched, they were about as big as a medium-sized dog.
If you jump on a time machine and have traveled back millions of years, you might come face to face with an adult Tyrannosaurus. Well, that would probably be more knee-length because dinosaurs could grow to huge sizes, but I digress. The important thing here is that you are afraid and either get eaten or run away.
However, if you come across a juvenile Tyrannosaur, you might be more inclined to pat it on the head rather than running for your life, as new research reveals that baby tyrannosaurs were about as big as a dog in size. average. The discovery is due to the discovery of fossilized tyrannosaur embryos that offer scientists a glimpse into the size of the creatures when they first crawled out of their shells.

As reported by CNN, the study, which was published in the Canadian Journal of Earth Sciences, is largely based on a jaw bone from a tyrannosaur embryo. Because so many tyrannosaur fossils have been discovered over the years, it often takes just one bone for researchers to determine the animal’s overall size. In this case, the baby dinosaur was about three feet long.
It’s a tiny version of a creature that might grow to over 30 feet in length as an adult, but three feet is still pretty big when it comes to baby animals. These dinosaurs came from eggs, and the researchers estimate that the egg that contained the dinosaur used for this study alone would have measured about 17 inches long. It’s a big omelet.
Of course, a baby predator is always a predator, so while a tiny tyrannosaurus was probably adorable, it could still do some damage. The creatures were born with all the tools they needed to procure their own food, with mouths full of teeth that would produce a painful if not fatal bite on small prey. However, as the debate rages on whether or not Tyrannosaurs were primarily hunters or scavengers rages on, it’s worth considering.
Finding out the size of a baby tyrannosaurus is actually just the tip of the iceberg to understanding what juvenile creatures looked like. Scientists have learned a lot about the parenting habits (and sometimes the lack thereof) of many different dinosaurs, but there is special interest in how tyrannosaurs were able to raise their young. In the years to come, maybe some of these questions will be answered.
