Ichthyodectes was a large fish that swam in the Western Interior Seaway during the late Cretaceous Period. It looked much like its larger cousin, the Xiphactinus, but was only about six feet in length. Ichthyodectes teeth were of medium size and were about the same size throughout the jaw.

The bone on the top of the head is the supraoccipital and was where major muscles attached. It was not a spike or horn as had been thought by some when first discovered.

Although not much is known about the life of Ichthyodectes, it has been established that it was preyed upon by sharks as evidenced by remains of it in a Squalicorax falcatus specimen.
