Maotianshan Shales fossil record. Phylum Porifera (sponges; 15 species) and Priapulida (16 species) are also well represented. Other phyla represented are Brachiopoda, Chaetognatha, Cnidaria, Ctenophora, Echinodermata, Hyolitha, Nematomorpha, Phoronida, and Chordata. Possible molluscs include "Wiwaxia" and "Nectocaris". About one in eight animals are problematic forms of uncertain affinity, some of which may have been evolutionary experiments that survived for only a brief period as benthic environments rapidly changed in the Cambrian. Chengjiang is the richest source of the lobopodia, a group including many early panarthropods, with six genera represented: "Luolishania", "Paucipodia", "Cardiodictyon"," Hallucigenia" (also known from the Burgess Shale), "Microdictyon", and "Onychodictyon".
Phyla lanceolata Phyla lanceolata Phyla lanceolata is a species of flowering plant in the verbena family known by the common name lanceleaf fogfruit or frogfruit. It is native to the southern half of North America, including much of the United States except for the northwestern quadrant, and much of Mexico. It is resident in many types of moist and wet habitat, including disturbed areas, such as irrigation ditches. It is a perennial herb growing decumbent in a matlike form with spreading, trailing stems up to half a meter long, sometimes rooting at nodes. The lance-shaped or nearly oval leaves are up to
