Researchers in Liverpool, England have been studying the jaws of the adult T rex in an attempt to determine just how strong their bite was.  They created a computer model using a process known as reverse engineering in their study.  Reverse engineering has been used to calculate the running speeds of various dinosaurs.

The team of scientists used models of the human jaw along with the jaws of a juvenile T rex, an Allosaurus and an alligator.  They took these models and scaled them up to the size of the adult T rex and although the strength of the bites did increase with the larger size, none of them came close to the force they computed of the adult T rex.

From all of the tests and simulations, the scientists calculated that the bite force of the adult T rex was equivalent to the force exerted on the ground when an average sized elephant sits down.  This is more force than any other animal living or extinct.

One surprising result of their study was that the juvenile T rex had a comparatively weaker bite than the adult when the difference in size of the jaws was figured in.  The difference in the bite force between the adult and juvenile was thought to indicate a possible change in feeding behavior as the huge reptile matured.  The researchers did not offer any explanation of what the feeding behavior difference may have been, but as a trained wildlife biologist, I have a theory that may fit the research data.

A younger T rex is much lighter in weight than an adult, thus possibly making the animal more agile and faster.  Speed and agility would have lent themselves to the lifestyle of a hunter.  But as the T rex grew in size and weight, it lost some of its speed and agility, forcing the adults to become more of a scavenger than a hunter.

Large scavengers tend to have powerful jaw muscles that allow them to bite through everything including bone.  Hyenas are a good example of a scavenger with tremendous jaw strength.  They hunt and kill when opportunity presents itself, much like an adult T rex may have, but their main source of food is scavenging and stealing kills from other animals.  Imagine a juvenile T rex or some other smaller theropod dinosaur making a kill, only to have a much larger and more powerful adult T rex come along.  I’m sure the smaller animals would readily give up its kill to save itself from certain death.

At Creation, the T rex may or may not have needed the powerful jaw muscles depending on what fruit and plant material it was eating.  If it was feeding on large gourds or even coconuts, then possibly the strong jaw muscles would have been very useful.  It’s also possible that the extra powerful jaws were developed after the Curse when disease and death entered Creation.  Once animals started dying, T rex may have started its scavenging lifestyle.

Yes, it’s all supposition, but it’s supposition made based on my knowledge of Scripture first and biology second.

Dragons or Dinosaurs DVD

Dragon images, legends and lore exist all over the world in many different cultures. There are numerous written accounts of encounters with real dragons, some dating back to the time of Alexander the Great.  Yet evolutionists dismiss them as nothing more than myths and legends.

But what if dragons were actually dinosaurs?

Evolutionists frequently use dinosaurs to discredit the Bible and undermine the Gospel of Jesus Christ.

Dragons or Dinosaurs? explores the evidences from around the world that indeed, dinosaurs were dragons and that they lived at the same time as man.  Listen to experts as they reveal historical facts such as stone carvings resembling a stegosaur made hundreds of years before their bones were discovered and identified.

This informative video gives answers to these and other questions that surround this controversial theory.
