Next in my line of old drawings is a non-palaeo one. I always liked drawing cars but was never good at it. So I'd doodle and try to practice from time to time. Here, I've got a selection of cars; a Subaru Impreza, some Japanese pick-up truck, a sedan, and another Japanese-style truck with a kind of near-future Sci-Fi anime feel. Incidentally, Smarty Pants is a product idea I had as a joke (though the technology isn't available to make it happen).
A quick divergence from my usual dinosaurs, and I shall talk about big cats today. This is because to my greatest delight, I had discovered today a wonderful book. It is called The Felidæ of Rancho La Brea (Merriam and Stock 1932, Carnegie Institution of Washington publication, no. 422). As the title suggests it goes into details of felids from the Rancho La Brea, in particular Smilodon californicus (probably synonymous with S. fatalis ), but also the American Cave Lion, Panthera atrox . The book is full of detailed descriptions, numerous measurements and beautiful figures. However, what really got me excited was, in their description and comparative anatomy of P. atrox , Merriam and Stock (1932) provide identification criteria for the Lion and Tiger, a translation of the one devised by the French palaeontologist Marcelin Boule in 1906. I have forever been looking for a set of rules for identifying lions and tigers and ultimately had to come up with a set of my own with a lot of help
