Submerged by MattMart Submerged by MattMart
Hyphalosaurus lingyuanensis, "submerged lizard," is a highly derived choristoderan from the Yixian Formation. It's close relative H. baitaigouensis (similar looking but with a longer neck and some proportional differences) is one of the most common vertebrates of the Jehol biota, with thousands of specimens known, many in private hands (I've personally seen a few in random fossil shops stateside, some with obvious "enhancements"). Some recent papers have finally given this guy the in-depth treatment it deserves, with a complete osteology, description of the skin and scales and reproduction (they were ovoviviparous, retaining soft-shelled eggs inside the mother but giving birth to live young. One newborn specimen even had two heads, the only Mesozoic example of polycephaly.

Hyphalosaurus means "submerged lizard," an apt name given that taphonomic evidence shows they preferred the deepest parts of the Jehol lake system. Contrary to early reports they are never found in the shallow, swampy waterways of the overlying Jiufotang Formation. The restoration here shows one individual in a dark lake bottom, scalation is based on preserved integument.

Great restoration of this unusual reptilian!  I wonder if two-headed ones ever reached adulthood ...

This little thing is cooler the more I know about it. A sort of little champsosaur.

Beautiful. Really beautiful.

I think your should put the texture you have on the background on the foreground elements too, though not as strong. It will help smooth the brushstrokes, and unify the picture.

I tried applying a subtle texture to the foreground figures, new version is on now. I still think the blending could use some work especially over the lighter portions but it definitely helped, thanks for the advice!

Thanks! I tried layering the same texture onto the foreground elements while it was a WIP, and it didn't seem to make much of a difference since the FG was already textured. But actually now that I think about it, I did tone town the FG texture later, especially on the twigs, so maybe I'll give this a shot...

Thanks! Though I think the tail came out a tad too short... despite the specimen I based it on having a below average length tail to begin with. The younger ones tails are crazy long. Need to do a juvi and two-headed neonate next :)
