Have you ever given any thought to what a pregnant Tyrannosaurus Rex might look like? This question that puzzled the scientific world for quite some time has been recently answered. A team of researchers found a pregnant T-Rex while examining a 68-million-year old femur.
When we thought we knew everything there is to know about the king of all dinosaurs, a new fossil comes around to smack us right in the face. This is basically what happened.
From school, we know that that the T-Rex was the largest land predator that ever roamed the Earth. Even though the dinosaur seemed quite bulky, its hind legs offered it an unparalleled agility. The dinosaur was quite the hunter despite the fact that it was blind as a bat.
Why is the T-Rex still a mystery, given what we know so far? Well, as far as reproduction is concerned, no one’s actually seen or discovered traces of a pregnant misses T-Rex.
A team of researchers from the University of North Carolina and North Carolina’s Museum of Natural Sciences have stumbled upon something unique. According to Mary Schweitzer, the lead author of the study, she and her team have allegedly discovered the earthly remains of a pregnant Tyrannosaurus Rex.
Well, don’t imagine that the scientist unearthed the fossils of a female T-Rex with a baby dinosaur in its womb. The evidence is much more subtle than that and, according to the team, the discovery has yet to be authenticated.
Here’s what they know so far. Following the discovery of a 68-million-year femur, the scientists from the two institutions decided to subject it to further analysis.
Upon a closer look, the scientists discovered the presence of an anomalous tissue formed on the femur. It was not long to figure out what was going on.
According to their declaration, the mysterious tissue found on the bone was, in fact, a medullary bone. This may not seem like much, but medullary bones in T-Rex’s only form when the female is pregnant.
The lead researchers explain that the extra tissue allows the female’s skeletal structure to support the additional weight from the eggs and even helps her while laying an egg.
However, Schweitzer and her team think that it’s too soon to say whether the tissue found in the fossil indicated that the Tyrannosaurus Rex was pregnant or not. She explains that certain afflictions found in theropods such as osteoporosis can induce the appearance of a similar tissue.
Like always, more research is needed to see whether the femur belonged to a pregnant female Tyrannosaurus Rex or not.
