Ambulacraria Ambulacraria Ambulacraria or Coelomopora is a Superphylum of invertebrate phyla which includes echinoderms and hemichordates; a member of this group is called an ambulacrarian. Phylogenetic analysis suggest the echinoderms and hemichordates separated around 533 million years ago. The Ambulacraria are part of the deuterostomes, a larger clade that also includes the Chordata, Vetulicolia and Saccorhytus. The two living clades with representative organisms are: The group Xenoturbellida (two species of worm-like animals) has previously been considered to be in this clade, but is now considered to be placed more basally among Metazoans. Fossil taxa that may lie on the stem lineage:
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
