Zhongjianornis an enlarged, keeled breastbone in more advanced birds. However, later analysis of the anatomy of "Z. yangi" cast doubt on this interpretation of the bird as very primitive. Research published in 2012 found that some of the apparently primitive features were due to poor preservation of the bones, and that "Zhongjianornis" is more similar in anatomy to primitive euornitheans like "Chaoyangia" and "Schizooura". A phylogenetic analysis showed that a very primitive position in the bird family tree for "Z. yangi" is unlikely given current evidence. Zhongjianornis Zhongjianornis is a genus of beaked, pigeon-sized birds from the early Cretaceous period of
Society for Scientific Exploration Society for Scientific Exploration The Society for Scientific Exploration, or SSE, is a group committed to studying fringe science. The opinions of the organization in regard to what are the proper limits of scientific exploration are often at odds with those of mainstream science. Critics argue that the SSE is devoted to disreputable ideas far outside the scientific mainstream. The Society was founded in 1982. Its first meeting took place at the University of Maryland, College Park in 1982. Of the SSE and its journal, journalist Michael D..
