The fossil of a fish much like a piranha appears to be the earliest flesh-eating fish. It was found in Germany. Having teeth similar to a piranha it lived 150 million years ago. Remains of its victims were found nearby. It mainly ate the fins of fish. Evolving to consume only fins was a survival mechanism. Fish that were attacked did not die immediately. They survived to provide a meal another day. The hunter's teeth were triangular. With serrated edges, they were ideal for cutting flesh. Initially, bony fish could only bite chunks of flesh out of prey or swallow them whole. Slicing of flesh appeared much later. The hunting method of the fossilized fish was identical to modern-day piranhas. Injuries to the attacked were the same. The ancient specimen was a sea dweller. Piranhas live only in fresh water. Oddly, some piranhas are vegetarians mainly eating seeds. They are a normal food for South American people who say they taste like any other fish. It is not understood why they

Extinction of the thylacine on the continent has not been critically analysed. However, the story on Tasmanian land is known. ◘1 thylacine an ◘1 Much has been said about the extinction of thylacines in Tasmania. There has not been much discussion about the animals demise on the mainland. A controversial claim about this is now doing the rounds.    ◙2 thylacine to extinction weather a thylacine ok caused to or extinction tasmanian ◙2 Though the Tasmanian tiger is classed as a carnivore, it survived mainly on carrion. Its jaws were too long to give a strong bite. Indeed, sheep killings were not done by the creature. Other introduced species killed native fauna as well as livestock.  ⦿3 extinction caused up to weather caused ⦿3 Thylacine mitochondrial DNA was obtained from bones in museums. Computer analysis supposedly showed changes in population size over time. Such projections are questionable and unproven in science. It is fairy tale stuff.   ⧗ w sex tasmania or ⧗

When a warmer climate spread across the world, mammoths were in deep trouble.  Melting snow together with predation by humans made the animals extinct.  There numbers dwindled to zero in 6,000 years.  A strange thing happened during this time.  The species tried to adapt and threw up countless mutations.  Most were destructive.   | ▶ optimum not stories news. | mutations mammoths killed ◀ | The long dark coat, so good as insulation from the cold, became like satin and light could shine through it.  They got severe irritable bowel syndrome due to their loss of smell.    It stopped them from mating due to protein changes in the creature's urine.    | ▶ | australian| mutations ◀ |     These changes are now known from two specimens in Siberia.  One on the mainland and another on a rock island.  It was the slightly later Wrangel Island specimen that had an over representation of genetic mutations. Those who want to save threatened species must now be careful. Inbreeding could
