I draw all of my digitally colorized illustrations 2.5 times - first as a quick watercolor, second when I laboriously draw everything with a real pencil, and a half when I color it in photoshop. Here's the sketch and finished illustrations of Ankylorhiza tiedemani: https://t.co/cBfoz4H093

Ankylorhiza is part of an early lineage of toothed whales before they start to seriously fuse and shorten thier verts for more effecient high speed swimming. Afaik the more normal cervical verts means they'd retain a more normal range of motion

Here's some of my graphite + digital illustrations of extinct marine fauna - each of these takes about 20-50 hours. Clockwise from upper left: Phiomicetus; Ankylorhiza; Psephophorus; Olympicetus

Ankylorhiza muestra características intermedias entre cetáceos primitivos y los odontocetos modernos, y se cree que pudo haber tenido un nicho ecológico similar al de las orcas actuales, alimentándose de presas veloces

For I naturally need to highlight our new paper on Ankylorhiza. Ankylorhiza means "fused roots" - most early diverging dolphins have double rooted teeth, but nearly all the teeth are single rooted - making it one of the first dolphins to evolve this condition.
