I am an artist, and I post a lot of my own art. I am also the Admin here at Sauropods.win, and a lot of my boosts will be great dinosaur (and other prehistoric animal) stuff from the other winners here.

A random artwork from my gallery:

"Life-sized Pterodactylus" — 2014

Pterodactylus was a little pterosaur that lived in Germany during the Late Jurassic, about 145 million years ago. It is known from several excellent fossils, which include soft-tissue impressions of it fur, wings, and crest. It is also a very pretty little animal.

Life-sized paintings make no sense on the internet, of course, because device-makers and software vendor never got together for a goddamn standard about how big things would be displayed because fuck everyone.

(Much like the “send something to someone right next to you” problem that they’ve fumbled for decades.)

Not that I'm bitter.

Thanks for your answers everyone. Looks like linen and casein might be the front-runner for now. I’m going to give it a go. It will be a conversation point when people ask me why my bike smells like rotten milk.

Thanks @amcewen

Does anybody know if there’s a traditional composite material that behaves something like fibreglass? As in fibre/fabric laid up in a binder of some sort to make a stiff material in arbitrary forms.

Paper mache is one but it’s too weak (I think, maybe there's a super version?). I'm considering things like cotton or flax in casein glue or pine resin... but I doubt it will work.

(And my last casein glue experiment stunk like rotten milk for weeks!)

@futurebird Yeah, I’m trying for biodegradable, so no epoxy!

john,
@john@sauropods.win avatar

@fastness Yeah, that's right. I'm not sure what they used for glue. Probably casein?

john,
@john@sauropods.win avatar

I should clarify, the point is to be biodegradable, I already know I can mix epoxies with flax fibre for a pretty strong composite, for example. But epoxies aren't biodegradble.

john,
@john@sauropods.win avatar

@futurebird Ah yes, lacquer. I've considered that, not sure about the expense, not sure about it's strength, led to me not trying it.

john,
@john@sauropods.win avatar

@amcewen Great, that is exactly the sort of thing I was looking for, So my flax+casein idea seems like the right track.

john,
@john@sauropods.win avatar

@Limnobotanik Huh, I always thought that was just vinyl - that's pretty interesting. Can it be made stiff?

john,
@john@sauropods.win avatar

@futurebird A part for my bike. Depends on how strong I can make it, but either just a mudguard, or a mudguard/rack/seat/battery-holding/trailer-towing complex.

john,
@john@sauropods.win avatar

@belehaa That would sure be one. Probably too brittle and heavy for my purpose (non-frame bike parts).

john,
@john@sauropods.win avatar

@paris I’v considered animal glues. Two things put me off - I'll need a lot of it to use it in a composite, and they are very susceptible to moisture, right?

john,
@john@sauropods.win avatar

@fastness Leather is actually a pretty cool idea, but I don't think I could practically work it at the size I need (I wouldn't fit in my oven).

john,
@john@sauropods.win avatar

@Tak That's an interesting one. I think I had some difficulty getting pitch when I was considering something along those lines.

john,
@john@sauropods.win avatar

@fritzoids It isn't, but I suspect it's probably not practical for me to work it at scale I want. I'd need to do a lot of joining and I very much doubt I have the skill!

john,
@john@sauropods.win avatar

@mgdm That sounds like some sort of starch glue maybe?

john,
@john@sauropods.win avatar

@paris A bike part. Mudguard+ other things depending on the strength.

john,
@john@sauropods.win avatar

@JonnyT @futurebird I had not heard of cow gum until now, but it looks like it's a latex glue. So I think it's biodegradable, but the latex glues I have stay really flexible (good for some things, not for what I want this time). Also they degrade in UV, which isn’t ideal, although could probably be worked around.

john,
@john@sauropods.win avatar

@JonnyT Probably PVA, right? Could be a starch glue too.

john,
@john@sauropods.win avatar

@JonnyT definitely sounds like PVA. Which is a great glue, and I use it all the time, but it’s not really biodegradable, probably (it’s complicated!)

john,
@john@sauropods.win avatar

@miekeroth Interesting, what is it?

john,
@john@sauropods.win avatar

@felichsdakatze How strong is it?

john,
@john@sauropods.win avatar

@markno how strong is shellac?

Somebody stop me registering this hilarious domain name for a project I'm not really ever going to do... please?

@mike @keesey No, Dinosauria is a word, making the pun(?).
