New Dino Discoveries Missing Link Between Predators

Two newly discovered dinosaurs may be missing links in a line of predators that lived some 160 million to 90 million years ago.An international team of researchers unearthed two alvareszaurian species from the Early Cretaceous—Xiyunykus and Bannykus.Found in Northwest China, the dinos’ unique anatomy (namely, an enlarged finger for digging into nests) places them somewhere in the 70-million-year evolutionary gap between Late Cretaceous insect-eaters and the group’s earliest known member, Haplocheirus.“The significance of Xiyunykus and Bannykus is that they … shed light on patterns of evolution within Alvarezsauroidea,” study co-author Corwin Sullivan, a University of Alberta paleontologist, said in a statement.“These specimens greatly improve the scientific community’s understanding of the early stages of alvarezsauroid evolution,” he continued, “and give us a better idea of what early alvareszauroids were like.”Specifically, they reveal how the animals’ diet shifted from meat to insects.The transition from a typical theropod forelimb configuration (long arm, three-digit grasping hand) to a highly specialized one (short arm, one-digit digging hand) implying a change from fleshy meals to small aphids.“The forelimbs show some adaptations for digging, which would later become more exaggerated, and some features of their skulls also resemble those of insectivorous alvarezsauroids,” Sullivan explained.Less modified hind limbs, meanwhile, suggest the dinosaurs’ arms and head underwent significant change before the legs.“There’s still a lot to learn about the early evolution of alvarezsauroids,” Sullivan, also curator of the Philip J. Currie Dinosaur Museum in Canada, added.The incomplete skeletons of Xiyunykus and Bannykus are currently under analysis. But researchers can only get so far with what’s on the table in front of them.“We’ll need many more fossils before we can be confident that we have a clear understanding of how alvarezsauroids, to put it bluntly, got so weird,” Sullivan said.The team’s research was published recently in the journal Current Biology.Another day, another dino-related discovery: Scientists used genomes of different species to determine how the chromosomes of the Velociraptor or Tyrannosaurus might have looked.

10 Things You Shouldnt Be Putting in Your Recycle Bin

first_imgStay on target Around 90% of American households recycle these days, which is a great thing. There’s just one little thing that needs work.Well, one little thing in addition to getting that number up another ten points. Many of us are tossing things into our recycling bins that we shouldn’t.That’s a big problem because a few bad apples really can spoil the whole bunch. Contaminated items can cause an entire load of perfectly good recyclables to wind up in a landfill.The solution is simple enough. We just need to be a bit more careful when we’re sorting.The Detroit Free Press recently spoke to some recycling industry insiders to find out what the most problematic items were. They compiled the top ten, and some of the entries may surprise you.For example, a lot of people don’t realize that tissue paper can’t be recycled, but it rounded out the Freep’s list along with paper towels.Plastic bags are on the list, too. They can get tangled in machinery and cause serious mechanical issues. They’re best left for dedicated bag recycling initiatives, dropped off at a participating store, or taken directly to a recycling center that accepts them.Your old garden hoses and extensions cords? They’re not meant for blue bins either. The same goes for wire clothes hangers in most areas, but many dry cleaners are happy to take them back for re-use… and that’s even better than recycling them.Other metal items can cause problems, too. Old auto parts may need to be taken to a scrap yard (where you may get a few bucks for them anyway) and you can probably take any old pots and pans you want to get rid of there, too.That retro-tastic stash of cassettes and VHS tapes you’ve been hoping might net you a tidy profit one day? When you finally decide to get rid of them, don’t put them with your recycling.Plastic utensils can’t be recycled, and neither can most cardboard pizza boxes. Not unless they somehow manage to stay grease-free while holding their delicious cargo.Styrofoam is another thing you should keep out of your bin, though that may change in the near future. A company in Montreal has figured out a way to turn polystyrene back into pellets that can be formed back into plastic.We’ve been able to make some amazing things from recycled products. Like chewing gum into sneakers, Nissan’s leaf battery solar kits, and wastewater that’s being turned into beer.
