A report submitted to the U.
Kuban Other alleged evidence for modern pterosaurs includes artifacts and rock etchings of questionable origin or very subjective interpretation. What is sorely lacking, besides convincing photos of extant pterosaurs, is any reliably documented forensic or physical remains such as carcasses, bones, eggs, nests, or tracks.
Indeed, the totality of evidence for LPs seems even less abundant and more equivocal than for other unconfirmed creatures or "cryptids," such as "Bigfoot" or the "Loch Ness Monster," which is probably why even among young earth creationists YECs and cryptozoologists, relatively few advocate the idea of living pterosaurs.

Janet Fikar Whitcomb and associates have suggested that mainstream scientists are unduly biased against the idea of living pterosaurs on the grounds that such finds would threaten conventional geology and evolution Whitcomb, a. However, this is a misguided notion, since the survival a remnant species from a group once thought extinct would be a wonderful discovery, but not the least problematic for evolution or an old Earth.
While one can argue that everyone including me has some bias, any I have does not exclude the remote possibility of living pterosaurs, even though I and most other scientists are properly skeptical for reasons already discussed. Nor do we "fear" the idea of extant pterosaurs as Whitcomb asserts; in fact, I like most scientists would wholeheartedly welcome such a find, as long as it was properly documented.
As evidence, when such "living fossil" finds have been made before, such as Latimeria a modern genus of lobed-fin, Coelacanth fish thought long extinct until one was caught off the coast of Africa inand Metasequoia Dawn Redwoodscientists were not dismayed, nor tried to cover them up, but the opposite: Moreover, representatives of many other groups that were alive while dinosaurs roamed the Earth are still with us today, including sharks and other fish groups, crocodilians, turtles, lizards, birds, small mammals, etc.
So, the focus of some YECs on finding living pterosaurs or other possible survivors of prehistoric groups, in hopes that this will confirm their young-Earth views and refute evolution is quite misplaced. What YECs actually need to accomplish this is essentially the opposite: This is not too much to ask, since YECism holds that most fossils were deposited together in a worldwide flood just a few thousand years, meaning that there should be countless thousands of such finds.
Therefore, the finding of say an Ordovician or Silurian pterosaur would, ironically, be far more problematic for mainstream geology than a modern one.
Likewise, Whitcomb's frequent lament that conventional scientists are blinded by a "universal-extinction dogma" that all dinosaurs and pterosaurs are extinct is readily dispelled by the fact scientists already accept that not all dinosaurs are extinct, since almost all modern paleontologists regard birds as a branch of feathered dinosaurs.
So, it is clear that scientific skepticism over the concept of living pterosaurs is not due to prejudice or dogma, but evidence - fossil evidence pointing strongly to the likelihood of pterosaur extinction, and lack of compelling evidence to the contrary.
Sightings General Considerations Many websites and several books relate numerous eyewitness accounts of alleged LP sightings in several countries, and many U. However, many entail ambiguous or inconsistent descriptions, which are often not fully compatible with known pterosaurs, or clearly incompatible with other creatures, especially when all factors are considered discussed further below.
Most important, none are accompanied by convincing photos or physical evidence. Even if we assume that all of the witnesses are honest, serious, sober, and sane difficult propositions to demonstrateit is usually difficult to rule out mistaken identifications.
A couple typical examples will serve to illustrate this allegedly more "credible" cases will be discussed later. They later described it as resembling a pterodactyl.

Forensic science is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure.. Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation.
While some forensic scientists travel to the scene of the crime. Comparison between the contentious imagery and the defendant in court has the considerable advantage that it will obviate any risk of conveying to the jury the fact that the defendant had a police record implicit in evidence of recognition by a police witness.
