La Huérguina Formation environment which presents an important aquatic and terrestrial flora (with many specimens of Charophytes, Montsechia, Weischelia or Frenelopsis) and diverse fauna, with specimens of at least five or six Phyla: Arthropods, Molluscs, Chordata and many vermiform soft bodied animals which might be Nemertines or Annelids. Among vertebrates the most abundant and diverse group are fish. The presence of mostly articulated skeletons, exceptional preservation of tissue and lack of any other signs of transportation may indicate that these are demic and autochthonous entities (meaning that they lived and died in the same place where they fossilized). Crocodylomorphs are the most abundant
Branching order of bacterial phyla (Woese, 1987) was not based on molecular phylogeny. Eukaryotes are a mosaic of different lineages: Consequently, in Woese (1987) the group is referred to as urkaryote. The clade composed of Archaea and the nuclear genome of eukaryotes is called Neomura by T. Cavalier-Smith Branching order of bacterial phyla (Woese, 1987) There are several models of the Branching order of bacterial phyla, one of these was proposed in 1987 paper by Carl Woese. The branching order proposed by Carl Woese was based on molecular phylogeny, which was considered revolutionary as all preceding models were based on discussions of morphology. ("v." Monera). Several models
