- Tyrannosaurs are the most iconic dinosaurs of all, but what they were like as babies has been the subject of debate and mystery.
- New research on infrequent tyrannosaurus embryos gives researchers a good first look at what large consumers of freshly hatched meat looked like.
- When the dinosaurs hatched, they were more or less as large as a medium-sized dog.
If you jump on a time machine and travel back millions of years, you may find yourself standing face to face with an adult tyrannosaurus. Well, it would probably be more like kneeling because dinosaurs could get to massive sizes, but I digress. The important thing here is to be scared and eat or run away.
However, if you come across a juvenile tyrannosaurus, you may be more inclined to stroke it on the head instead of running for your life, as new research reveals that baby tyrannosaurs were about as big as a baby. medium sized dog. The finding comes thanks to the discovery of fossilized tyrannosaurus embryos that offer scientists a view of the size of the creatures when they first came out of their shells.

As reported by CNN, the study, which was published in the Canadian Journal of Earth Sciences, is based largely on a jaw bone of a tyrannosaurus embryo. Because so many tyrannosaurus fossils have been discovered over the years, often only a single bone is needed for researchers to determine the overall size of the animal. In this case, the baby dinosaur was about three meters long.
This is a small version of a creature that could grow to more than 30 feet in length as an adult, but the three feet are still quite large when it comes to baby animals. These dinosaurs came from eggs and the researchers estimate that the egg containing the dinosaur used for this study would have been about 17 centimeters long on its own. This is a great tortilla.
Of course, a predatory baby is still a predator, so while a small tyrannosaurus was probably adorable, it could probably cause some damage. The creatures were born with all the tools needed to secure their own food, with a mouth full of teeth that would produce a painful or even lethal bite on small prey. However, as the debate over whether tyrannosaurs were primarily hunters or scavengers deepens, it is worth considering
Discovering the size of a baby tyrannosaurus is really just the tip of the iceberg when it comes to understanding what creatures were like when they were younger. Scientists have learned a lot about the breeding habits (and sometimes lack of them) of many different dinosaurs, but there is a special interest in how tyrannosaurs may have bred their young. In the coming years, some of these questions may be answered.
