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
Phyla lanceolata 6 centimeters long and have toothed or partially toothed edges. The inflorescence, arising on a peduncle several centimeters tall, is a spherical spike of flowers which elongates into a cylindrical form as the fruits develop. The tiny, densely packed flowers are white, sometimes tinged with blue or purple. It is similar to the related species "Phyla nodiflora", but differs in having much longer and more pointed leaves. Both species are common as weeds and in the ornamental environment. Phyla lanceolata Phyla lanceolata is a species of flowering plant in the verbena family known by the common name lanceleaf fogfruit or
