have read the original document, here is the link:
investigation is about two skulls from modern Panthera members (no fossils here). The specimens are large but not
exceptional (250 mm and 218 mm, respectively). Some of its characteristics
suggest a different animal that show affinities with both jaguar and leopard,
but other ones put them in the jaguar group only.
of the study is that these are just normal jaguars (Panthera onca), although they have some unique characteristics on
it. The reported coat color could not be proved, but if it’s true, there it was
just an aberrant coloration and did not represent a different species (for the
important to mention that no DNA study was performed as the skulls were boiled
to its preservation. However the investigators suggest that maybe more advance
genetic analysis could obtain some DNA for future studies.
that preoccupied me is this:
“In conclusion, our morphometric analyses
indicate that the Peruvian skulls do not represent potential new species. In the case of the
‘Peruvian tiger’, the possibility remains that a jaguar skull was provided in
place of the original, however. Should additional cranial
material purportedly belonging to mystery big cats be discovered, morphometric techniques
such as those employed here should allow their identities to be determined.”
Who do you
interpret the bold part?
seems that there are no “new” cat species for the moment, just a couple of
weird jaguars of average size.
