Thaumastosaurus gezei
This potentially Eocene fossilised frog is a beautiful rare mummified like fossil, that shows the skin and eyes of the amphibian, opening a portal that brings us back in time.
It was found in what is known today as the Quercy Regional Natural Park, southwestern France. Unfortunately the exact location of the cave where it was found is still unknown. Having all the elements preserved for this information is priceless to palaeontologists, so many eager Quercy explorers have tried in vain to discover its origins, hoping to find other animals preserved in the same condition. Rosa attended such an expedition in 2015, where she had the opportunity to hold this exquisite treasure.

This Eocene Paleoenvironement (36 million years ago) is set in the Quercy, southwestern France, you can see Thaumastosaurus gezei sunning himself in a small pond surrounded by Nymphaeaceae (water lilies) with horse tail to the left, a fern plant to the right hosts a Dragonfly Odonata, to the back you can see a reconstruction of a curious primate called Adapidae peeking from behind a rock as variations of fern plants and Eocene trees fill the background.
This drawing is all done by hand with pencil, watercolour, markers, acrylic paint and pen. I used photos that I took myself of the dragonfly and water-lilys. The Eocene frog is a beautiful but very rare fossil that shows skin and eyes of the amphibian. I added an ammonite fossil in the rocks that dates from the Middle Devonian (just for fun). Hope you enjoy this picture as much as I had fun to draw it.
