the loosely defined term "supervolcano" has been used to describe volcanic fields that produce exceptionally large volcanic eruptions. thus defined, the yellowstone supervolcano is the volcanic field which produced the latest three supereruptions from the yellowstone hotspot; it also produced one additional smaller eruption, thereby creating the west thumb of yellowstone lake 174,000 years ago. the three supereruptions occurred 2.1 million, 1.3 million, and approximately 630,000 years ago, forming the island park caldera, the henry's fork caldera, and yellowstone calderas, respectively. the island park caldera supereruption (2.1 million years ago), which produced the huckleberry ridge tuff, was the largest, and produced 2,500 times as much ash as the 1980 mount st. helens eruption. the next biggest supereruption formed the yellowstone caldera (~ 630,000 years ago) and produced the lava creek tuff. the henry's fork caldera (1.2 million years ago) produced the smaller mesa falls tuff, but is the only caldera from the snake river plain-yellowstone hotspot that is plainly visible today.

bullet::::- sauron appears in the "hulk and the agents of s.m.a.s.h." episode "savage land", voiced by steven blum. when the agents of s.m.a.s.h. arrive in the savage land, sauron leads an army of laser-mounted pteranodons in an attack upon their jump jet. during the fight, sauron drains the energy from one of the pteranodons where he manages to knock a-bomb off the jump jet. saruon states that he and his dinosaurs survived extinction and that man's time on earth will be at its end. while sauron controls devil dinosaur into attacking a-bomb and red hulk, she-hulk and skaar find sauron's lizardmen allies using a special drill in the super volcano. sauron is alerted about the situation at the super volcano and commands devil dinosaur into finishing the job. sauron engages skaar in battle as he tries to mind control him and drains the energies of him and she-hulk. hulk, red hulk, a-bomb, and devil dinosaur arrive where hulk fights sauron while the others work to stop the drill. sauron then tries to drain hulk's energy which doesn't work. after the drill was destroyed, a weakened sauron flees from the pteranodons. in the episode "into the negative zone," it is revealed that the leader supplied the weapons and technology for sauron's plot to cause the super volcano to erupt. in the episode "mission: impossible man," sauron leads an army of prehistoric sea creatures to attack a seaside amusement park. he ended up fighting the agents of s.m.a.s.h. and impossible man. when impossible man manages to trap sauron, his powers end up absorbed by sauron who uses them to attack the agents of s.m.a.s.h. as the two-headed compound hulk (impossible man's combining of hulk and red hulk) is punching sauron, he sprouts three more heads. sauron even summoned fin fang foom (who was the only reptile that sauron couldn't control) to help him. after his absorption of impossible man's powers wore off, sauron tried to absorb fin fang foom's powers only to be knocked out to sea. following the two-headed compound hulk punching fin fang foom out to sea, it landed on sauron who was still in the water. in the episode "monsters no more," sauron appears as a member of leader's agents of c.r.a.s.h. in the episode "days of future smash: the dino era," sauron was the king of the dinosaur-dominated timeline caused by leader. he is served by an ankylosaurus called general thunder lizard rossasaurus in his plot to exterminate the primitive humans. with help from el diablo and spider-raptor, the agents of s.m.a.s.h. freed the primitive humans and overthrew king sauron which ended with him falling into a pit of giant spiders. after hulk thwarted leader's plans in the mesozoic era, the dinosaur-dominated timeline shifted to the next timeline.
