New extinct shark species named for ’80s arcade game Galaga

A new species of prehistoric shark emerged from rubble that once surrounded Sue, the world’s largest and most complete Tyrannosaurus rex, Smithsonian magazine reports. Researchers reported the new species, named Galagadon nordquistae for the resemblance of its tiny, triangular teeth to the space invaders from the 1981 arcade game Galaga, this week in the Journal of Paleontology. Archaeologists unearthed Sue from the Hell Creek Formation in South Dakota in 1990, but kept the rock removed from the fossil for further study. A volunteer found the strange teeth while sifting through Sue’s leftovers. The finding suggests the ancient creek might have connected to the ocean, allowing this prehistoric shark to swim inland.
