Mosasaurs breathed air and were powerful swimmers that were well-adapted to living in the warm, shallow epicontinental seas prevalent during the Late Cretaceous Period. Mosasaurs were so well adapted to this environment that they gave birth to live young, rather than return to the shore to lay eggs, as sea turtles do.
The smallest-known mosasaur was Carinodens belgicus, which was about 3.0 to 3.5 m long and probably lived in shallow waters near shore, cracking mollusks and sea urchins with its bulbous teeth. Larger mosasaurs were more typical: mosasaurs ranged in size up to 17 m. Hainosaurus holds the record for longest mosasaur, at 17.5 m.
Mosasaurs had a body shape similar to that of modern-day monitor lizards (varanids), but were more elongated and streamlined for swimming. Their limb bones were reduced in length and their paddles were formed by webbing between their elongated digit-bones. Their tails were broad and supplied the locomotive power. This method of locomotion may have been similar to that used by the conger eel or sea snakes today. The animal may have lurked and pounced rapidly and powerfully on passing prey, rather than hunting for it.
Skeletal drawings of three types of mosasaurMosasaurs had a double-hinged jaw and flexible skull (much like that of a snake), which enabled them to gulp down their prey almost whole, a snakelike habit that has helped identify the unmasticated gut contents fossilized within mosasaur skeletons. A skeleton of Tylosaurus proriger from South Dakota included remains of the diving seabird Hesperornis, a marine bony fish, a possible shark and another, smaller mosasaur (Clidastes). Mosasaur bones have also been found with shark teeth embedded in them.
Based on features such as the double row of pterygoid (“flanged”) teeth on the palate, the double-hinged jaw, modified/reduced limbs and probable methods of locomotion, many researchers believe that snakes and mosasaurs may have had a common ancestor. “From Wikipedia”

    These images you do would be tremendous in book form- I think there would be such a market for that xx

  • Thank you Anita, I hear it is hard to get a puplishing company to do a book of art work.

    I think it would really hard, but this seems so specialised and has an educational factor too- I can see it in a really nice coffee table book. I think there are some published artists here who may have helpful hints (I wouldnt have the first clue).
    I know you can make your own books and order one by one on Lulu and Blurb sites (because I fancy trying that myself).
    I think its quite pricey but really nice for a keepsake (signed by the artist/author too).
    This one I think looks stunning framed up also xxxxxx

  • Thank you for the information Anita, I will look in to it.

    Thank you

    Wow Walter – you are very accomplished – I have alwasy been an oil painter and have yet to venture to digital painting – it seems like one huge blank canvas and I havent worked up the courage/initiative to start – thanks for the comment on my photo – it let me know about you great work – dave

  • Thank you Dave.

    I started out painting with oil and acrylic, then got interested in digital art. It was a challenge I enjoyed. I do miss the feel of the oil going on the canvas and the blending of the colors.

    I still have a ways to go to master 3d art, I learn more everyday.

    Great work on this Walter, Do check out the Blurb site that Antia mentioned they are great with their books, have done one though them the end product was spot on the only thing would be to lighten your images slightiy when doing a book they tend to come out abit on the dark side but apart from that well worth it.

  • Thank you my friend, I am going to look into that.
