They classified the genus as belonging to a new biological order, Sinosauropterygiformes, family Sinosauropterygidae, within the subclass Sauriurae. These proposals have not been accepted, and "Sinosauropteryx" is generally classified in the family Compsognathidae, a group of small-bodied long-tailed coelurosaurian theropods known from the Late Jurassic and Early Cretaceous of Asia, Europe, and South America. Below is a cladogram showing the placement of "Sinosauropteryx" within Coelurosauria by Senter "et al." in
Calamus caryotoides as follows: "The thin flexible trunks of this (and other) climbing palm made ideal building frames, or rope and string when split. The young shoots were eaten to cure headaches." Calamus caryotoides Calamus caryotoides (also "Palmijuncus caryotoides"), more commonly known as fishtail lawyer cane is a North-East Queensland tropical forest climbing palm with very thin () flexible trunks; no crownshaft; small spikes; dark green, glossy, fish-tail shaped leaves reaching up to high ( spread); and very thin hooked flagella. It tends to clump and grow up into the shaded understory of Queensland's wet tropical forests, and is a close relative
