Paleoart and DINOSAURS!!!

I have discovered the world of podcasting and love it! There are a few that I like (and I'm open to more -feel free to suggest!) and on the way back to work from Rotorua, I was listening to an episode from 99% Invisible about 'paleoart' which I found fascinating (as I usually do) as well as a great opportunity for our older children to learn about inference.
I know that's a skill that is taught in reading but can be a bit more difficult to understand in science. The TKI science capabilities website (www.scienceonline.tki.org.nz) talks a bit about the first capability Gather and Interpret Data by talking about the gathering data as directly observable or measurable whilst the interpreting data bit is making meaning of the observation. As soon as children start to explain something, it's usually an inference!
Anyway this week's podcast was about the art of drawing dinosaurs and looked at how they were first drawn which was as big, cumbersome creatures that never moved. In fact one picture I was looking at showed two dinosaurs comatose as well as biting one another!

This has moved on to the current dinosaurs which are very fluid and, as one person said, looking shrink-wrapped with lots of muscles as if they headed off to the gym three times a week. Jurassic Park has sort of followed this model, particularly in the early days.

Now people drawing dinosaurs is changing again, and here's the inferences bit... We really have no idea what the dinosaurs really looked like. We do have some fossils with remains of muscles, fat and scales on. We also have fossils with what looks like proto-feathers on. But we don't know whether all dinosaurs had all of these! If you look at modern mammals, there's quite a wide selection even in the same type of animal! So this has given artists leeway to experiment. Here's what a dinosaur may have looked like that lived in the colder regions:

I think this is interesting for two reasons. One, it can support children in being a little more critical of dinosaur art... How can the artist be sure it was purple with yellow stripes (which a dinosaur big book that I had in my classroom did!)? How can I be sure it didn't? If I want to infer, can it just be my imagination or does it need to be justified? So what does inference really mean then? Secondly, it can help children really get their head around observation and inference. We can work out that a triceratops had three horns and the shape of it's skeleton. We may also be able to tell how long the tail may have been... well, at least the bones bit! But the rest is inference! It may have had quills on the top of its head. It might have had a bright red frill... Could children look at a picture and a fossil and work out the observation and inference bits?
The podcast and a couple of the articles talk about what we might think modern animals may look like to the future paleontologist -there won't be an elephant trunk fossil, camel hump or the blubber of a whale to show them what these creatures really looked like. In fact how do we know the dinosaurs didn't have a big hump?
I love the picture of swans they draw as I already think of them as violent creatures!
One has speared a tadpole, neither have feathers or wings as they didn't fossilize...
The articles are quite interesting and I think this would make a great reading activity for the children. If I was to do it, I would draw the science out of this... So what are we learning about science? My daughter knows I'm quite the critiquer and has become one herself. Recently, she watched a BBC dinosaur clip and paused it to tell me that the commentator was talking about the behaviour and appearance of the dinosaur as if it was true rather then "We believe that these particular dinosaurs played guitar late at night whilst wearing sombreros" (and I so want to find this as a picture!). This is what we want for our children: to learn how media report science, how science actually is, and what observation and inference are.
Do the inferences mean that the artist is wrong? Not necessarily, but we need to explain why we have drawn particular features. Although I remember the older dinosaur books having some pretty exotic colours, I never really thought it was legit... I sort of thought they'd be more camouflaged and I didn't think trees would be those colours. Mind you, they might have been anyway! I do remember that early efforts to model the iguanadon were completely wrong due to putting the fossil together incorrectly -could this still happen today?
So, have a read of some articles, look at some of the pictures, have a go at drawing the creature that would fit a particular skeleton (like a whale, camel or rabbit) without sharing what the creature is and then get the children to justify their efforts. They might even like to have a go at drawing what a dinosaur might have looked!
Here's some of the places I went:

https://99percentinvisible.org/episode/welcome-to-jurassic-art/ (This is the podcast one -I would certainly recommend it for the children to listen to as it is a safe one with some interesting ideas... and I like the idea of students listening to podcasts!).
I had to finish with this picture just because it looks lovely! Apparently most art of dinosaurs usually had them eating or fighting and this was one of the first pictures of them sleeping (although I'm wondering if they might have slept standing...).

So enjoy!
Keep on sciencing!
