Spinosaurus Mum takes a break..

Well, I couldn’t leave well enough alone and kept throwing more time and energy into the Spinosaurus sketch! In some ways it touches back to the first paleo gig I did a few years ago for Tor Bertin who was reviewing Spinosaur material.

Back then I’d hoped to paint the living animal, but had to satisfied with doing some studies of the jaws instead.(I still had more fun than any sane person should have)

Recently inspired by the skeletal reconstruction by Scott Hartman with Andre Cau and Jamie Headden I thought I’d have a stab at painting the new look properly.

Hopefully I did the guys’ hard work some service, the new sail extends much further down the tail. The pose has no scientific verification, though I did opt for something different than the usual explosive action poses we usually find Spinosaurus in.(at least it isn’t beating up Tyrannosaurus!)

What can I say? It’s a mum, eating a snack on her break. With a cheeky Ornithocheirid pterosaur waiting for some scraps. You might have noticed the little guy has changed since the last post, well, I discovered there wasn’t really a way for it to be clinging on with the wings in that position. Here’s a before and after…

Science at Home: Multicoloured Flowers, ‘What crap will lizards eat?’ and the birth of Mothra!

I grew up on a diet of Attenborough documentaries(where I learned BBC does documentaries like no other), ‘In the Wild with Harry Butler’(where I learned to always put the rock back and drunk pygmy possums are easier to get along with) and some wildlife show that had Lorne Greene narrating and ‘Jesu, Joy Of Man’s Desiring as it’s theme music but I can’t find reference to it anywhere (which taught me slow motion wildlife, Lorne Greene and classical music are pretty epic together). By the way, if anyone can remember what this show was called let me know!

My kids on the other hand are getting large doses of ‘Deadly 60’, ‘Barney’s Barrier Reef’ and a rather cool show called ‘Backyard Science’. The really great thing about ‘Backyard Science’ is that it shows kids doing experiments themselves and discovering how stuff works. It wasn’t long before Gabby was pestering me to try out an experiment I hadn’t seen. It involved taking a white flower with plenty of stem, splitting the stem in two and putting each side of the split into a separate cup. You then put water and different food colouring in each cup and wait overnight. This was our result:

ImageAwesome! Of course the great thing about this is then Gabby asked why it happens. Then we had to find out!(it was almost like I was some kind of responsible parent or something)

Around the same time Isaac and I were encountering skinks in the backyard and he decided that we should feed them as the pesticide barrier or ‘Death Zone’ around our house meant they had fewer insects to eat. So in the spirit of scientific experimentation and being too lazy to chase moths around the back yard I checked what was in the fridge.

Left over Lasagne.

I can’t begin to describe the sacrifice we were making for science, just as words cannot do justice to the lasagne made in our household. Thankfully we didn’t need much as skinks are very small.

We placed the lasagne in places we’d seen the lizards basking and waited. It didn’t take long for the lizards to start chowing down! We were hooked!

The following weeks we tried sausage(eaten), cheese(eaten) and watermelon, filmed with inappropriate music below…

Yuh I know, it’s *just* like ‘Jurassic Park’! (this skink is smarter than T-Rex though, I’m pretty sure it can find something to eat even if the the prey stays still)

The kids are also curious about bugs we find, we’d look up different things uncovered from under rocks or beaten senseless against an outside light .

We’d seen some really big cocoons(10cm long) poking out of holes in trees lately and the kids and I were wondering what emerges from them. During a recent party at a friend’s place we stumbled across another cocoon which was full of what is scientifically known as (orange)goo. The occupant was sitting right next to it… MOTHRA!

ImageTo demonstrate how impressed Mothra was at being disturbed while it recovered from getting out of the cocoon it deployed a large tube from its underside and squirted the same goo a quite impressive 50cm or so. The kids didn’t love that part much.

Gabby really wanted to know what it was that had sprayed her with goo, turns out it was a Wood Moth.

I guess the point of all this is that kids really do value knowledge in a way I think many adults forget to do. It’s easy to get caught up in the day to day routines of work and ‘civilisation’ and forget that there’s a whole lot of stuff going on around us that is worth knowing even just for the sense of wonder, if not the reward of understanding how the pieces of the puzzle of life go together.

What I did on my Summer Vacation #2: Swimming with the Tuna

Every couple of years we travel the 2000km to Port Lincoln in South Australia to visit with family. Port Lincoln is a big fishing town, with the last 2 decades spent ‘farming’ tuna as a value adding venture in response to lower catch quotas.

In the last few years some local tourist operators saw the tuna farming set up, with its captive fauna, as a more accessible form of this. Fun fact: Live shots for ‘Jaws’ were filmed off Pt. Lincoln.

This year we were determined to be tourists in the place we grew up, and since my daughter Gabby and I are such animal nuts we hopped on a boat and went out to a tuna enclosure to get in the water!

The set up was pretty impressive, with the main enclosure containing (delicious looking) tuna surrounding a smaller enclosure swirling with smaller (yummy) species. There were also underwater viewing areas and touch pools containing a variety of kid friendly (and tasty looking) creatures like prawns.

So we suited up…

Gabby is smaller than the fish we were about to swim with, which would make me a less tempting target if things went all 'horror movie' on us!

What you see from above...

.. the mayhem when you get in!

Once you’re in it becomes abundantly clear just how well adapted these animals are to their environment. As we clumsily flopped about the tuna moved their 60kg bulk between us effortlessly. I was surprised by a couple of things, the mobility of the eyes was much greater than I would have thought. The tuna wouldn’t allow you to touch them, if you reached a hand out even toward their tail they would slip out of the way, they could clearly see what I was up to even when I thought I was well out of line of sight.(one of the guides had been a ‘tuna cowboy’ and caught them by hand, you’d have to be bloody quick)

The other amazing bit of anatomy was the way all of the fins, including the yellow ‘spikes’ along the dorsal and ventral posterior body, all had slots to fold into. The Tuna could become bullets at will! Here are two pictures which hopefully show it in action…

Fin sticks up!

Fin goes down!

While you’re in the water you get to hand feed the tuna whole pilchards, which are tossed to you on the surface and you have to hide them until you’re ready to hold them out for the fish.

Another surprise was in store, on one close feeding pass I could feel the tuna’s teeth through the thick diving gloves I was wearing. For some reason I’d always thought tuna engulfed their prey and had only rudimentary teeth, bit wrong there!

The experience was great and they allowed us plenty of time to experience the different fish. For some reason I couldn’t help but start seeing tuna steaks and crumbed prawns, probably should have had a bigger breakfast.

Next time around Gabby and I are keen to swim with the Sea Lions, and I’m also hoping to hop in a cage and get up close with a Great White Shark.

Listen to the Impartial…

A while back I pointed out the importance of listening to the scientist when making scientific illustration, they know their stuff, it’s their job. It’s also important to listen to a trusted friend or two, someone who brings a fresh pair of eyes, preferably they haven’t had contact with the artwork before.. You may not always like what they have to say, but if you’re making visual communication like art or illustration then having a small sample audience can give you an idea if your message is getting across. It’ll become clear very quickly when something doesn’t ‘read right’.

One of the benefits of marriage is you get a convenient audience/viewer/victim to show artwork to. I’m lucky in that Sanja, though now the best book keeper in Tasmania, used to do a fair bit of art herself. I’m also lucky that when it comes to saying stuff about my work, Sanja will just come out with something that strikes her as wrong, usually starting tactfully with “Is that supposed to be…”.

At that point I’ll usually roll my eyes in exasperation, knowing that Sanja has pointed out a critical aspect of the work that I’ve overlooked, knew I could have done better or just plain fluffed.

So with Sanja’s comment on my last post in mind I’ve adjusted the sail on the Spinosaur, which I knew wasn’t right but needed that impartial eye to sort drive it home. Here’s a little update to show the new angle, with the ‘undercoat’ exposed to see just how much the thing has shifted!

ImageFor those without a trusted feedback person, you can go far doing a few tricks that allow you to see your work in a different light.

Horizontal Flipping of the image often fools the brain into thinking it’s seeing something new. In software this is pretty easy, in the real world use a mirror to view your artwork(an old trick). It’s pretty amazing how composition issues suddenly appear!

Desaturation really helps sort out your values. I use an adjustment layer in Photoshop which I can just turn on and off to see a black and white version of my painting so I can make sure I’m using a full range of values.

The Old Squint Test, yup, narrow your eyes and look through your lashes. This obscures detail and makes the values and composition much more important to reading the image.

Take a step back. Yep, you can literally and figuratively get too close to what you’re doing. Getting stuck into the rewarding stuff like detail too early can lead to overlooking your main masses, values and composition. In software zoom out and make the image a thumbnail. Does it still ‘read’ well? Zooming out of the image allows you to assess perspective more effectively too.

Even better, take a step away from your monitor/canvas/paper, walk around the room, have a 30 minute break and come back. Does the image still work?

Experienced visual communicators will be pretty familiar with these techniques, and likely have even more to draw upon. Check out David Maas’ blog for a look at how a real pro dismembers an artwork in truly analytical fashion.

Now I just need a palaeontologist to come along and tell me the spine didn’t have that much flexibility…..

Lazy Afternoon

Having a lazy afternoon here as the temperature scales the dizzy heights(for Hobart) of 30C degrees. Nice excuse to stay indoors until the sun drops low enough to get out the sprinkler and go berserk with the kids in the back yard.

Also a nice excuse to get the sketch book out and do a thumbnail of a Spinosaurus having a lazy afternoon lunch!

ImageBased on the new skeletal reconstruction by Scott Hartman who took advice from Andre Cau and Jamie Headden. Most notable is the length of the sail, which now goes well down the tail.

I’m pretty sure there are some proportions out of whack, and the posture surely brings into question the flexibility of the spine and hips, as well as the volumes going through the torso.

I’d like to do more with this initial image, though it’ll have to join the queue forming of ‘stuff I want to do’ and paid work!
