Prehistoric Sea Monsters Poster |
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.
