Oldest steak knives found, according to ABC News in Science and Fossil Science 10 February 2014. Kirstin Brink and Robert Reisz of University of Toronto have studied the teeth of large fossil reptilian creatures named Dimetrodon, which are believed to have lived between 298 million and 272 million years ago, some 40 million years before meat eating dinosaurs evolved. Brink and Reisz found some of the teeth had serrated edges, like steak knives. According to Reisz, “The steak knife configuration of these teeth and the architecture of the skull suggest Dimetrodon was able to grab and rip and dismember large prey”.
As well as teeth with serrated edges, Dimetrodon also had teeth with cusps, raised points on the crowns like those of mammals. According to the ABC, “Its sharp, serrated teeth allowed Dimetrodon to rip into prey much larger than itself. Not surprisingly, this ravenous carnivore was at the top of the terrestrial food chain during its existence in the early Permian Period”. Reisz commented: “Teeth tell us a lot more about the ecology of animals than just looking at the skeleton. We already know from fossil evidence which animals existed at that time but now, with this type of research, we are starting to piece together how the members of these communities interacted”. The ABC article goes on to say: “Based on other known animals living at the time of Dimetrodon’s existence, the toothy predator probably hunted prey such as large fish, aquatic amphibians, and certain land animals, including reptiles. It might have also snacked on insects that were around then”.
Editorial Comment: Actually, serrated steak knives can be used to cut up ay food – just come to this editor’s house when all the other knives are in the dishwasher.
Furthermore, when we invite vegetarians to our place for a meal, the fact that we have mosquitoes, raise chickens and have dogs all alive at the same time doesn’t tell you anything about which ones we eat… score zero for the mossies. So just because this creature is found buried with fossil fish, amphibians, reptiles and insects does not mean it ate them either.
Neither do sharp teeth alone enable an animal to kill prey that is larger than itself. It takes more than sharp teeth to make an animal a successful hunter. The real bones show us that Dimetrodon did grow to be about 15ft long, but have a good look at them, then think through what structure you need to be built for speed and agility. That’s what real investigation actually is. It definitely seems to have been a long, low slung animal with short legs, a long tail and a large sail-like structure projecting upwards from its back. But since this animal is extinct, no living scientist has witnessed it eat anything, so there is no reason why it could not have eaten plants with teeth that had serrated edges or cusps.
The God who created is insistent He was there and His witness statement is all animals originally ate plants, (Gen 1: 31) and it was only after the world degenerated due to human sin and God’s judgement that animals became violent, and hunted one another (Gen 3 – Gen 11). Faith choice again folks – not just facts. Faith in evolutionists who weren’t there vs faith in the Creator who was. (Ref, diet, dentition, reptiles)
