Some reports that I get have some similar characteristics to other witness testimony taken that feature a noticeable protruding jaw. In most of these reports the witness describes a Sasquatch type creature with a ape-like jaw while other witnesses are describing something completely different like the dogman. The reports that I have received about a protruding jaw are not common but I do get them, most of these reports with this facial feature seem to be limited to a specific region of the United States. In some cases of the reports of a protruding jaw we are dealing with another “type” of Sasquatch but in some cases the protruding jaw could be prognathism.
A condition known as “prognathism,” a trait found in apes and in ancient human fossil skulls.
Prognathism is a condition in which part of the jaw protrudes, causing the chin or upper jaw to jut forward. It can be genetic, as in the case of the famous Hapsburg jaw, or it can be the result of a medical condition. Depending on the severity of the condition, various treatments can be used to reduce the protrusion.
Chimpanzees and other apes display what is known as “facial prognathism,” where the face protrudes beyond the top of the skull. Human faces are relatively flat in comparison. Additionally, a chimpanzee’s skull has no forehead and has prominent brow ridges above the eye sockets, whereas a human skull has an obvious forehead and chin. In fact, humans are the only primates with chins, so this is a telltale difference between humans and any other ape. It is important to note that I do not recall one witness who had a Sasquatch encounter describe a chin. In every instance the witnesses describe a very wide jaw.
Human teeth are small and relatively regular in size throughout the jaw in comparison to chimpanzee teeth, and the jaw is smaller overall. Chimpanzees have sharp, pronounced canines in the upper jaw that sit against large lower premolars in the lower jaw. These large teeth are used for threat displays and as weapons. Also, the mastoid process, where the jaw muscles attach to the skull is more distinct in human skulls than in chimpanzee skulls.
In most of the reports I have taken from witnesses that describe this facial prognathism or protruding jaw, the witnesses that were close enough or in some cases too close describe the creature growling or showing its teeth to reveal large pronounced canines. In other reports I have taken witnesses describe a very large wide jaw but not a protruding jaw. In those cases the witnesses describe large square like teeth, most say they do not recall seeing pronounced canines.
Regarding Sasquatch, the theory concludes that we are simply dealing with multiple species from the same family tree.
