No teeth arouse the interest of Aurora collectors more than the giant fossils left behind by the earth's greatest selachian preditor -- the megatoothed sharks of the genus Carcharocles aka Carcharodon. The proper name for this genus is beat around in the section Great White Ancestory and will not be discussed here.

C. chubutensis (AMEGHINO, 1906)
    aka C. subauriculatus

Lingual image of upper anterior, upper lateral, lower anterior, and lower posterior Carcharocles chubutensis from the Pungo River formation. Lateral cusplets are evident but not spectacularly prominent.

C. megalodon (AGASSIZ, 1837)

Having produced the largest (over 6 inches) teeth of any shark, it is no wonder that more collectors pursue this fossil than any other at Aurora. Its presence in the mine's Yorktown formation explains the popularity of these tailings. There's a story of a novice collector asking an old timer the easiest way to find the Yorktown Formation. His response was, "right after the next hurricane, enter the mine at night with a flashlight, when you see footprints, you're in the Yorktown".

The below specimen was found near the bus at the end of an otherwise poor collecting day.
