One characteristic unique to Olmec culture is that they produced stone heads of colossal size. These were carved in Basalt and all of them display unique facial feature so that they can be considered portraits of actual rulers. The heads can be nearly 3 meters high and 8 tons in weight, and the stone from which they were carved was in some cases transported 80 km or more using huge balsa river rafts.
They also liked to mix animals to create wonderful creatures such as were-jaguars, a cross between a human and a jaguar, which may have been their supreme deity. It is known they also liked to drink chocolate.

Replaced how? If you mean like the Roman empire, that would be incorrect. Both empires considered each other Roman and both empires considered themselves Roman. So when the west fell, the Byzantines did not 'replace' the western Romans in being Roman. Instead, they just kept on being Roman as their western counterparts fell. However, for a period, the Byzantines did manage to reconquer parts of the Western Empire and even Rome, but that was relatively short-lived. In that case, you could argue that the Byzantines sort of did replace the western Romans in being the Roman empire with Rome in its possession. However, that is a stretch in my opinion.
In short: False, the Eastern Romans did not replace the western Romans as they were both seen as Romans, just with different governments.
