Giant softshell from Pakistan, colored (2014). by jwmorenob Giant softshell from Pakistan, colored (2014). by jwmorenob
This is a colored version of my earlier Drazinderetes drawing, which can be seen here: jwmorenob.deviantart.com/art/G…

I used the techniques suggested by Jaime Bran bran-artworks.deviantart.com/ to digitally enhance the contrast of the drawing. Then, I used the technique explained here (antoniohg.com/tutoriales/color… to color the image.

In the late middle Eocene of Pakistan, the giant soft-shell turtle Drazinderetes tethyensis [6] swims near the muddy bottom of the Tethys sea. D. tethyensiswas a big turtle, the total length of its bony carapace was estimated in about 800 mm long and 700 mm wide [6]. A softshell entoplastron from the same area could belong to a larger specimen, with a bony carapace about 1200 mm long and 1100 mm wide. The crab Lobocarcinus indicus [7] assumes a defensive posture as the turtle gets close, and the big venomous snail Conus colossus crawls pacefully on the sea floor, among shells of bivalves [1, 3] and gastropods [2, 3]. Two basilosaurid whales [4, 5] swim in the background. 

I want to thank Javier Luque (University of Alberta) for the advise on fossil crabs.

A finales del Eoceno medio en Pakistán, la tortuga gigante de caparazón blando Drazinderetes tethyensis [6]nada cerca del fondo lodoso del mar de Tethys. D. tethyensis era una tortuga grande, la longitud total de su caparazón óseo fue estimada en alrededor de 800 mm de largo y 700 mm de ancho. Un entoplastron de tortuga de caparazón blando hallado en la misma área pudo pertenecer a un especimen mas largo, con un caparazón óseo de alrededor de 1200 mm de longitud y  1100 mm de ancho [6]. El cangrejo Lobocarcinus indicus [7] asume una postura defensiva al acercarse la tortuga, y el gran caracol venenoso Conus colossus se arrastra pacíficamente sobre el lecho marino, entre las conchas de bivalvos [1, 3] y gastrópodos [2, 3]. Al fondo nadan dos ballenas basilosauridas [4, 5].

Quiero agradecer a Javier Luque (Universidad de Alberta) por los consejos sobre cangrejos fósiles.

I´m doing a Masters in paleontology right now. So you could say I´m studying to become a paleontologist.
