One of the frustrating aspects that paleontologists face when studying dinosaur fossils is the odd lack of sexual dimorphism in the ancient creatures — being able to tell the difference between male and female individuals based on their physical features. However, one method of telling whether an individual specimen is a female or not has been uncovered, with the confirmation of a Tyrannosaurus rex fossil that came from a pregnant female.

"This analysis allows us to determine the gender of this fossil, and gives us a window into the evolution of egg laying in modern birds," says the study’s lead researcher, North Carolina State University evolutionary biologist Mary Schweitzer.

Researcher Andrew Collins has recently published an article outlining the discovery of the link between carvings that appear on a small bone plaque, and the megaliths at the Göbekli Tepe archaeological site where the plaque was found. These carvings may have provided us with a clue that implies that the researchers that have been studying the site may be seeing the site’s orientation entirely backward.

The construction of the megalithic monument at Stonehenge has long been explained as has having been built in numerous stages, spanning a period between 8,000 and 1,600 BCE. The structure of the site has seen various upgrades over the ages, from it’s beginnings as a series of pine markers, to the multi-ton bluestones that are visible today. However, archaeologists have recently uncovered evidence that the stones used there may have been taken from an earlier monument, closer to the stones’ origin in Wales.

In recent decades, researchers have found significant evidence of correlations between a variety of human events conditions and solar activity. Such ancient events as the collapse of Rome, the Hundred Years war and the 20th Century wars seem to be correlated to periods of intense solar activity. For example, a huge solar storm took place just days before the start of World War II–an event predicted in 1917 by the apparition at Fatima. During the collapse of the Roman empire, solar events were recorded with great frequency, as was the case during the Hundred Years War.
