After the extinction of the non-avian dinosaurs 66 million years ago, hyaenodonts were the main predators on the African continent.The newly discovered animal is called Pakakali rukwaensis, the name derived from the Swahili term "pakakali," meaning "fierce cat," and "rukwaensis," the word for the Rukwa Rift region of the Great Rift Valley in southwestern Tanzania. They coexist for a few million years, then the hyaenodonts are driven to extinction and we're left with 'The Lion King.' With Pakakali, we can start to unravel that extinction. Were they adapting differently to a drier, more open landscape?The fossil gives paleontologists a glimpse of hyaenodont anatomy before modern carnivores invaded the continent, revealing that Pakakali was about the size of a bobcat.Based on the findings of the study, hyaenodonts may have been pushed to become more specialized meat-eaters due to competition from other species.Evolutionists generally feel secure even in the face of compelling creationist arguments today because of their utter confidence in the geological time scale.Even if they cannot provide a naturalistic mechanism, they appeal to the "fact of evolution," by which they mean an interpretation of earth history with a succession of different types of plants and animals in a drama spanning hundreds of millions of years.A key technical advance, which occurred about 25 years ago, involved the ability to measure the ratio of C ratio from approximately 1% of the modern value to about 0.001%, extending the theoretical range of sensitivity from about 40,000 years to about 90,000 years.The expectation was that this improvement in precision would make it possible to use this technique to date dramatically older fossil material.
In particular, they discovered the very slow nuclear decay rates of elements like Uranium while observing considerable amounts of the daughter products from such decay.In more than a decade of exploration, RRBP researchers have described the habitat Pakakali called home along with many other animals that occupied the ecosystem."The environment containing Pakakali reveals a fascinating window into extinction," says Nancy Stevens, co-author of the study and a paleontologist at Ohio University.The Bible, by contrast, paints a radically different picture of our planet's history.In particular, it describes a time when God catastrophically destroyed the earth and essentially all its life.
