Both Anisacanthus and Holodiscus are what level of classification?
Holodiscus Holodiscus (syn. "Sericotheca") is a genus of flowering plants in the family Rosaceae, native to the Americas, from southwestern British Columbia, Canada and the western United States south to Bolivia.
Ankylopoda Ankylopoda is a clade that contains turtles and lepidosaurs (Tuatara, lizards and snakes) and their fossil relatives. This clade is supported based on microRNAs as well as the fossil record. Stem-turtles and lepidosaurs have unique skull elements and features not seen in archosaurs (represented by extant crocodilians and birds).
