Triarthrus novoaustralis

quick little thingo of the new aussie trilobite: Triarthrus novoaustralis

trying to be more okay with imperfections in my art, i still struggle with focusing on fine details which dont really add much to the final composition, even here i admittedly do it a bit

Triarthrus is an Upper Ordovician trilobite found in New York, Ohio, Kentucky, and Indiana, eastern and northern Canada, and Scandinavia. It is the last of the Olenid trilobites, a group which flourished in the Cambrian period. T. eatoni have been found in the Beecher's Trilobite Bed, Rome, New York area with soft body parts preserved in iron pyrite. Pyrite preservation has given scientists a rare opportunity to examine the gills, walking legs, antennae and digestive systems of trilobites, which are rarely preserved. Triarthrus is therefore commonly used in science texts to illustrate trilobite physiology.
