A307 - Prehistoric Sea
Monsters
The
Earth’s oceans were once the hunting ground of real sea
monsters that could have frightened even the most fearsome
Hollywood creations. This fascinating new poster provides 22
striking and scientifically accurate illustrations of the
most well known. These aquatic monsters include the
terrifying Dunkleosteus, a giant fanged fish more
than 33 feet long, with jaws like a primitive slicing
machine for devouring armored prey; the 66-foot long
Plesiosaurus, a ferocious long-necked aquatic reptile
that was the apex predator of the Jurassic oceans; and the
massive Megalodon, the largest-known shark, at least
three times longer and larger than today’s great white
shark.
Surprisingly, fossils for many of these aquatic species have been found
in central and western North America. That’s because 148
million years ago, this area was covered with a vast inland
sea. It dried up about 70 million years ago, leaving behind
many spectacular fossils. This poster contains a map of this
sea and the above explanation. |
