From: Never met a scientific illustrator? Meet Carol. by Kalliopi Monoyios at Symbiartic.

Original source: Journal of Vertebrate Paleontology 1992 cover illustration of the reconstruction of the skull of Stegosaurus stenops in left lateral view. Ink on paper, by Carol Abraczinskas.

Stipple is a pen and ink technique used in scientific illustration that utilizes millions of tiny dots to create areas of shadow and light. This stipple drawing of the skull of Stegosaurus stenops by Carol Abraczinskas appeared on the cover of the Journal of Vertebrate Paleontology in 1992. It’s a favorite teaching tool of Abraczinskas’s because it tests students’ observational skills. One missing dot prevents this illustration from being complete. Can you find it? To check if you got it right, see the original post for an enlarged view of that detail.
