Description The Upper Cretaceous beryciform dinopterygid Aipichthys velifer, in a school of its own kind.

I know a reasonable amount on this fish, mainly because it was part of a geology project I did last semester. We (the class), took a field trip to the fossil beds of Hjoula and excavated away. Our assignment was to take around three specimens, identify them (at home, of course), and write a report on them. I landed Aipichthys velifer, the prawn Carpopenaeus callirostris, and the bizarre congrid eel Enchelion montium.

I did a small painting to accompany the report; I recently dug it up and fiddled around with it in photoshop for the result you see above. I couldn't choose whether to classify as it as "traditional" or "digital", but, since I started from a painted base, I went with "traditional".

As you can see, Aipichthys was a deep-bodied, laterally flattened fish. I imagine it as a colorful reef-dweller, moving between corals, algae, rocks, whatnot. The color scheme is based, more or less, on its closest modern-day relatives - the squirrelfish.

Note that the main fish's dorsal fin is clipped - this reflects the absence of the fin on my fossil.

Thanks! I was trying to get a feeling of depth here, so I hope it worked.

Watercolor on this guy, no? I love it...Did you duplicate the fish and then blur the copies for the background? Whatever you did, it's very effective--gives a real life-like fidelity to the foreground figure. Beautiful!

Right first time! Watercolor, then copy+paste, resize, and blur, inserting "wash" layers of blue between each fish.

re: wash layers--That's a really good idea! I wish I had thought of that for some of my recent color "aquatics," like the Aguana and Pteroskate. I'll have to try it next time...

Nice work. Reminds me of Hatchetfish (at Wikipedia: [link] ).

I would've gone with a more cyan/grey/bluegreen water than the royal blue you chose.

I like how you used color-saturation and blurring to indicate distance.

With this kind of skill, why not do some good for the public-- like filling in blanks in the Wikipedia encyclopedia, or replacing ...errr... (insert euphemism here) like this placeholder art:

I'm still working on getting the right colors on water. I didn't want the same color as I did for the mosark, so I did blue instead.
Thanks!

You're right about the pictures though.

Dude, it's ok.
It''l be ages before I have anything done to submit to the contest.
I've been pretty tired lately & after this contest is over (when every that'll be) I'm totally gonna go on a personal holiday.
I've been doing too much for other people & not enough for my self as far as my art is concerned.

the details are marvelous. I can see clearly the squirrelfish influences in the colors and the texture.

hmm....I really wonder why deep-bodied, laterally compressed fishes are staple inhabitants of a coral reefs....something involving maneuverability I suppose ?

๐Ÿ‘: 0 โฉ: 2

elegaer In reply to tentaculus [2008-02-29 19:28:10 +0000 UTC]

Manouevrability - they can go forwards and backwards in very small spaces. Reefs are very 3d environments, and that ability to change direction, go wherever and get out of wherever is a key adaptation.
You'll notice that a good few deep-bodied reef fishes also have extended mouth areas to make the most of this, getting food from relatively inaccessible places.

Deep-bodied fishes have been part of coral reef ecosystems since the Devonian. In all the fossil reef communities we know from that time onwards, there have been deep-bodied fishes of similar morphotypes occupying the same ecological niches, even though these fishes have changed dramatically in underlying anatomy over the millennia.

Ahhh these things aren't in books You only learn them while you're researching LOL, and I'm not sure - actually, I'm pretty sure, no-one else has actually made much of a study of morphology of reef ecospace. There's a guy called Bellwood in Australia that works a lot of such things. He's cool.

Sphenacodon In reply to elegaer [2008-03-01 10:52:47 +0000 UTC]

Absolutely, it's the maneuverability. I found that out last week (yes, I'm speaking in a sheepish tone).

Nature tends to follow the rule that if it ain't broke, don't fix it.

Oh yes. Actually, one of the big themes of my PhD was exactly this - looking at the morphology of reef fishes through geological time. Especially deep-bodied one. It's fascinating.

Thanks! It's the stripes, I think...

Probably they're more maneuvarable, and the shape lets them slip between narrow cracks and hide in seaweed.
