Talk of a “chickenosaurus” lit up the science world last week when researchers announced they had modified the beak of a chicken embryo to resemble the snout of its dinosaur ancestors. But although some experts have lauded the feat, a beak is just one of many modifications needed to revert a chicken into a dinosaur.
Given these obstacles, how close are scientists to creating a dino-chicken? Learn here
Archaeornithoides was a maniraptoran of questionable rank (the troodontid bit is under debates) from the Djadokhta Formation beds in Mongolia, dating back to the Campanian age of the Late Cretaceous, about 75 million years ago. There aren’t a lot of remains of this animal, though the skull was only about 5 centimeters long, indicating that the body would have been about 50 to 60 centimeters long, making it one of the smallest non-avian dinosaurs. It was very birdlike, and it may be a juvenile of an already described genus, but it is unlike anything else and thus may be a valid genus. The rear portion of the skull showed damage from the teeth of a mammal, indicating that it was fed on by a mammal, though it could have been actively hunted or scavenged on.
Borogovia is another not well known troodontid from the Maastrichtian age of the Late Cretaceous, about 70 million years ago. It was found in teh Nemegt Basin of Ömnögovi Province, Mongolia. It is known from lower leg fragments, and it would have been about two meters long. There really isn’t anything else known about this dinosaur.
