It's said that you learn something new every day. Sometimes the knowledge one gains can seem pretty mundane. But today, Twitter user @OptimoPrincipi managed to rock our world with an informative thread about ancient Roman paleontology. The short thread is an eye-opener for anyone who thought the science was, well, modern. Turns out that Roman "fossil hunters" were fascinated by the bones of the "monsters" that pre-dated humans, even going as far as to create replicas of the extinct creatures. It's a wonderful look at the inquisitive minds of the past, and a testament to the apparently rich history of archaeological discovery.
