My first Xiphactinus Vertrbra
Found 12-15-02 - TEXAS
The Vertabra isn the picture above is from the Xiphactinus.
A fish that lived about seventy million years ago, in a vast, shallow
sea that stretched across
center of the North American continent. It was one of the most ferocious
inhabitants of that ancient sea.
The
most impressive part of a Xiphactinus is its rather bulldog-like expression,
with its upturned
jaw and giant, fang-like teeth. The jaw was very mobile, capable
of opening wide to take in large-sized prey.
Xiphactinus'
pectoral fins were held out by solid bony fin rays, giving the appearance
of wings. Its body
was long -- fifteen to twenty feet -- and there were more
than 100 vertebrae along its backbone.
Its tail was deep and forked, attached to the body at a narrow base.
All of these attributes
indicate that Xiphactinus was an extremely fast, powerful swimmer
and an active, efficient predator. Other
Xiphactinus fossils have been found with very large fish inside
the body cavity, swallowed whole.
