As the Jedi master Qui-Gon Jinn once said, Theres always a bigger fish. Or in the case of the Triassic Period, theres always a bigger aquatic reptile, as this incredible fossil demonstrates. New research published in iScience offers the oldest direct evidence of megapredation in the fossil record, in which an apex predator feeds upon formidably sized prey. The fossil, found at a quarry in Guizhou province of southwestern China, appears to show adidas campus a 15-foot-long 5-meter ichthyosaur pronounced ick-thee-oh-sore shortly after feasting upon a 12-foot-long 4-meter thalattosaur. Regrettably, the ichthyosaur probably died shortly after its meal, having bitten off more than it could handle. Ichthyosaurs were dolphin-like aquatic reptiles that emerged during the Triassic. This particular specimen belonged to an ichthyosaur species known as Guizhouichthyosaurus tangae, which nike dunk low grew as long as 33 feet 10 meters . Its presumed prey, a thalattosaur species called Xinpusaurus xingyiensis, was more lizard-like, with four limbs that it used to air max 1 paddle through the water. The new fossil is the first direct evidence to suggest at least some species of ichthyosaurs were apex predators, similar to orcas today. Illustration showing the shape and relative size of the animals involved.

Recent research into the health effects of the plastic-making chemicals phthalates has reignited concerns about low sperm counts. But the evidence is far from conclusive. salomon zapatillas Recent research has reignited concerns that exposure to chemicals from plastics might be to blame for low sperm counts in young men. I share the concerns about the high prevalence of low sperm counts one in six young men , and my research is directed at trying to identify what causes it. But whether plastics are to blame isnt a simple matter. Plastics are part of the fabric of our everyday lives and perform many essential functions. Without their thousands of uses, many of which are not obvious to us, our modern world could not function as it is. Plastics bring everyday benefits whether through childrens toys, the insulation around electrical wiring, their utility in food containers/wraps or their widespread use in medical products from blood bags, gloves and syringes, to the coating of some tablets and cap adidas originals mujer sules. But are there hidden dangers of plastics to human health, especially to male fertility This is a surprisingly difficult question to answer, not least because everyone is exposed to chemicals that derive from plastics. This means we dont really have an unexposed group control against which to compare. Most people probably dont understand how we are exposed to chemicals from plastics. After all, we dont eat the plastic wraps around food or chew electric wiring. Plasti adidas originals cisers are chemicals use
