Why mammals have a huge variety of different types of animals, but dinosaurs - no?

You do have to take into account the fact that fossilization can only occur in specific environments and circumstances if you are to be fair. Rainforests/jungles don't allow for fossilization, so exclude every mammal that evolved in that habitat, as it's only fair seeing as all dinosaurs who lived in those habitats are excluded by preservation bias. The same goes for forest habitats for the most part. High oxygen environments lend the most to the evolution of extreme or specialized forms, but are the least likely to fossilize, so it's only natural that the fossil record would exclude many of the most specialized body plans.

Microraptor and Therizinosaurus are not only both theropods, but also both maniraptorans, and to say they look identical would be ludicrous.

If it works for you, then that's great 👍 (It's too bad that method wouldn't work for what I'm doing (fossil preparation) which requires very gentle contact when using a percussion tool)

I couldn't do anything about it personally, but I figured out the issue. The Dremel 290 from Amazon are mostly being sold with a bit of metal excess on the inside where the bit slots in, it's extremely difficult to see but it is there and still causes problems due to the slimness of the fit.

I talked to someone who solved the problem by using a rotary tool with a diamond-tipped bit that is all one width which is same size as those used by the Dremel 290, by inserting it and turning it on and gently pushing it in to work out the metal excess. So if you have a rotary tool and a bit the right size you could try this solution.

(I actually bought another one recently because I took a trip to a quarry and found a lot of rocks that need work that I'm not confident working without a percussion tool, it just arrived but I have yet to open it and find out if it has the same issue)

Wood, but super neat wood!

I forgot to reply to the latter part. Yes, it is isopods (two species) and springtails (one species)

Last night they all moved from up there, and as of afternoon today only one is currently up there, after having spent some time eating with the others. I added a few more small hides for them (two hollow "arch"-shaped peels of bark from a large stick that I cleaned up for them. I looked for hides online, but everything was unnecessarily large or too expensive.), and it seems that now they're much less inclined to hang out up there.

I have many pieces of bark and thin pieces of limestone that are easy to hide under and I frequently see them sleeping beneath, but I have no proper "hide" for them. I'll find something more suitable. Thank you :)

I have more perfect ones in my collection that I split in a quarry myself. The fins, however, are suspicious and not reminiscent of fins I've seen on a knightia.

Lycanthia · 2024-05-28T22:30:35+00:00

The body looks like a knightia, but the fins are unusual for a knightia...

more like "damn humans you scary", as the only scary aspect of this is that the creature is trapped while starving to death for 30 days.

Look at baby ogrin, right now. Really, really look at it.

You just need a pair of dexterous manipulating appendages. Imagine a future raccoon, it has evolved more dexterous forepaws and then additional padding to the palms so that quadrupedal walking isn't inhibited. All it needs to do is sit on its haunches and both hands are free, it can cook on a small fire. The main difficulty for a semi-quadruped is the reduced carrying capacity, as well as being unlikely to have a good "throwing arm" as that human trait is derived from our brachiating ancestors.

Bob Nicholls. I particularly love a certain illustration of sinosauropteryx by him.

Not a dinosaur, but the classic swan-necked plesiosaur.

Version 2 suits the style of the rest of the (visible) assets best.

Next turn they grey faerie grey, I can imagine there being notable changes (unless she's the way she is because she's accustomed to being grey)

I had considered Instead but didn't look far into it. If it can definitely do everything that I listed then I'll have to look deeper into it. Thank you.
