Apparent Meteorite Hits Managua, Nicaragua, Leaving Crater But No Injuries

A wire report from AFP says that an explosion heard in Managua last night, and a 40-foot crater evident today, are evidence that the city was the impact site for a small meteorite that struck Saturday night. The photos are not very exciting at a glance, which is a good thing, considering that a dirt crater and no injuries is probably the best outcome if a meteorite strikes the city where you live. From the article: The meteorite appeared to have hurtled into a wooded area near the airport around midnight Saturday, its thunderous impact felt across the capital. The hit was so large that it registered on the instruments Strauss’ organization uses to size up earthquakes. “You can see two waves: first, a small seismic wave when the meteorite hit Earth, and then another stronger one, which is the impact of the sound,” he said. Government officials and experts visited the impact site on Sunday. One of them, William Martínez, said it was not yet clear if the meteorite burned up completely or if it had been blasted into the soil. “You can see mirror-like spots on the sides of the crater from where the meteorite power-scraped the walls,” Martínez said. (The same news, in slightly shorter form, from the AP.)

      Really? Do you have a reference for the research?

      If it's true that T.rex is closer to chickens than to pheasants, peafowl, and other Phasianinae, it would mean that the Phasianinae family dates back to before the K-T disaster. This would sorta imply a major reorg of the Therapsids, as well as the entire Aves class.

      So it's be interesting to read about the research on this discovery.

      This was all over the mainstream press last April. I was echoing their over-simplified characterizatoin of the research.

      It's actually "closest living relative among the set of genetic databases they tested", I.e. chickens, sheep, etc. Chickens happened to be a bird they tested, with aminno acid sequences far closer to those of the collagen recovered from T. Rex - nearly identical, in fact, than those of things like mammals. So don't expect this to re-write taxonomy - or to mean that chickens were any closer - or farter - from T. Rex than their close relatives such as phesants.

      Of course there's other evidence that birds were around well before T. Rex. So it may turn out that chickens are closer relatives to T. Rex than, say, bluebirds. (Or maybe bluebirds will turn out to be closer, once they're compared.)

      A quick google search turned up the following paper

      I wouldn't go so far as to say that chicken is the closest living relative to the T-Rex, just that it is the closest in sequence similarity to this particular collagen protein, out of all of the protein sequences known in 2007 (chicken could have been the only bird represented in the database at the time, but I am not going to take the time to look into this).

      I just searched the GVQGPPGPQGPR T-rex collagen sequence given in the text against the NCBI nr database, which is pretty comprehensive. It yielded the following Collagen alpha-1(I) chain perfect matches:

      Brachylophosaurus canadensis [dinosaur]
      Tyrannosaurus rex [dinosaur]

      Sarcophilus harrisii [Tasmanian devil]
      Monodelphis domestica [Gray short-tailed opossum]

      Corvus brachyrhynchos [American crow]
      Gallus gallus [Chicken]
      Manacus vitellinus [Golden-collared manakin]
      Pseudopodoces humilis [Ground tit]
      Anas platyrhynchos [Mallard duck]
      Geospiza fortis [Medium ground finch]
      Acanthisitta chloris [Rifleman]
      Columba livia [Rock dove]
      Melopsittacus undulatus [Parakeet]
      Falco peregrinus [Peregrine falcon]
      Falco cherrug [Saker falcon]

      So, that's 11 birds, 1 other dinosaur, and 2 mammals (one placental, one marsupial). The list gets bigger if we relax the sequence similarity cutoff. Based on this single fragment of a sequence, we can infer that T-rex is generally more closely related to birds than to mammals or lizards (and no lizards made the top-hit list), since there were a lot more bird matches than mammals (and the lack of mammal hits is likely not due to lack of sampling relative to birds). This is a big inference to make from a single fragment of a single protein, but I'm reasonably confident that further analysis of additional T-rex sequences would strengthen this finding.

      If more sequences have been published since 2007, then perhaps we could get a better idea of which modern bird T-rex is most closely related to, but there is no way to determine this from just the single example sequence above. We cannot say with any confidence that T-rex is more related to chicken than to any other bird, unless a much more thorough analysis is performed using a lot more data. Perhaps this has already been done, but I haven't taken the time to hunt for additional literature.

      If more sequences have been published since 2007, then perhaps we could get a better idea of which modern bird T-rex is most closely related to,

      On skeletal structure grounds, T.rex has been considered a sister group to all birds since the 1960s or so. On the basis of it's forearm structure, T.rex is a theropod dinosaur, but probably not a maniraptorinan theropod dinosaur. All birds however are considered maniraptorian theropod dinosaurs.

      We don't have a good understanding of the initial evolutionary radiation of the birds, between approximately the early Late Jurassic and mid-Late Cretaceous, when we find evidence of the early roots of some modern bird groups such as the ratites. There's no particular reason to think that any modern bird is more closely related to T.rex than any other. There probably is one such, but we don't have (and are very unlikely to ever get) enough evidence to really be sure of the family tree to that degree of accuracy. It's like asking if Ronald Reagan is more closely related to Emperor Hirohito, Osama bin Laden, Otzi the Iceman, or Barak Obama.

      I suppose I should add an Australian Aborigine and an Amerindian to that list, just to even out the range supplied. Let's say Montezuma (he of the Revenge, for the Amerind) and Ernie Dingo (an Australian Aboriginal TV character, according to my Australian colleague).
