Back in 2013, I posted a picture of the 25 foot long pliosaur known as Megalneusaurus, which swam in a shallow sea that once covered the central part of North America during the middle and late Jurassic Period. The illustration that I put up was based heavily upon a skeletal drawing of Liopleurodon, it had hardly any detail, and the skull was shockingly shrink-wrapped. Not my best work.

I’m happy to say that I have recently done a revised drawing of this 25-foot long marine reptile, and I think that it’s a substantial improvement over the earlier illustration. Here is the “new and improved” version…

This drawing was made in 1/20 scale with No. 2 and No. 3 pencils on roll paper, with some touch-up tweaking on my computer. From the tip of its nose to the tip of its tail, this animal measures 15 inches long, which would make it 25 feet long in real life. As for the fish swimming around it for protection, they’re just generic fish, I suppose. I tried to find images of fish fossils from the Sundance Sea, but I couldn’t find anything worthwhile.

Hope you enjoy it. Please like and comment.
