Jurassic
Anchiornis
Anchiornis huxleyi
The catalogue presents Anchiornis as a omnivore member of Troodontidae that lived during the Jurassic, between 160.0–155.0 Ma. Its estimated range is 0.3–0.5 m in length and 100–200 g in mass, giving a practical sense of scale. Reference material comes from Tiaojishan Formation, Liaoning, China. Size and mass are approximations and may change with new fossils or methods.
