HYPOTHESIS

STUCK IN THE MUD

• Theory- The dinosaurs died because their feet got stuck in the mud. It is invalid because...
• Lots of dinosaurs were found laying on their sides
• If the dinosaurs had been trapped in the mud, as they struggled their heavier legs would be buried more deeply and their bodies would be upright.

VOLCANIC VIOLENCE

• Theory- The dinosaurs were surprised by an erupting volcano. They can't breath in the hot, swiftly moving clouds of ash and sulfurous gases. This hypothesis is invalid because...
• Geologists studied the rocks for a mineral (silica) found in volcanic explosions and found none.

ASTEROIDS FROM OUTER SPACE

• Theory- The animals that the dinosaurs eat are becoming hard to find. Weak and exhausted the dinosaurs fall, one by one and do not get up. This theory is invalid because...
• A small amount of a mineral found in 65 million year old rock (iridium) has been found in the rock, but so far there hasn't been any irregular amounts of I amounts of iridium been found in the rocks.

POISONED WATER

• Theory- A group of dinosaurs gather at a spring-fed pool of water is poisoned. One by one they fall to the ground. The same thing happens the next day. This theory is invalid because...
• If the dinosaurs were poisoned some poisons might still remain in the bones.
• Geologists found a poison in the rocks called arsenic. There are 2 problems with the arsenic theory. 1. We don't know when the arsenic came into the rocks. 2. Fish were found with the dinosaurs. Could they have survived the poison.

A FEARSOME FLOOD

• Theory- The dinosaurs are sleeping under some trees. It's been raining for days. The water goes up no over the river banks. They are caught and drowned by the flood. Some climb the valley and survive. Another storm begins and new water and mud flow and cover the dinosaurs before the predators can arrive. This is invalid because...
• How do you explain the dinosaurs with their necks curved to their tails. This position only happens when a dead animal is left in a field long enough undisturbed for its muscle and ligaments to shrink.

WATER WORRIES

• Theory- The sun has been shining for days. Fish are trapped by the hundreds in small puddles. The dinosaurs scoop up the fish. But the dinosaurs need water. Hundreds die as they crowed around the last of the puddles. This theory is invalid because...
• The bones are not cracked, like they spent a lot of time in the sun. They suggest that there was a drought and then a flood.

TOO LITTLE WATER- THEN TOO MUCH

• Theory- Many of the dinosaurs die during a drought. When a sudden rainstorm breaks the drought, the dinosaurs are trapped and die. They are buried until 1947 when erosion removes their blanket of rock. This is valid because...
• In the rock that the Dinosaurs were found in, the mud was cracked with heat and then the dinosaurs bones weren't cracked .
• This might not be the corrected answer but it is the closes answer.
