English: Drawing of a Tchernyshevioides ninae trilobite, order Agnostida, family Hebediscidae, based on two photographs as printed in the Treatise on Invertebrate Paleontology, Part O, Arthropoda 1, Revised, Trilobita, vol. 1 (1997), figure 243,3a/c. Specimens from Tian-Shan (Sulyukta region) Siberia. Cephalon based on a holotype.
Cephalon and pygidium are drawn from separate photographs. The relative size of these parts and the distance between them are best guesses by the artist, but not necessarily correct to life.
