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:
Subgroups of Amish Amish". In the following, subgroups of Old Order Amish are listed from conservative to progressive: The Nebraska Amish are perhaps the most conservative group of Old Order Amish. They live mostly in Pennsylvania but they also have one small settlement in Ohio. Around 1880, Bishop Yost H. Yoder led nine families from Juniata County, Pennsylvania, to Gosper County in south-central Nebraska, founding an "Old Order" settlement that would last until 1904. Yoder went back to the Kishacoquillas Valley in Pennsylvania in 1881 to assist a conservative Amish group. Because bishop Yoder was living in Nebraska for some time, and the
