The return of Dave the Dot to Dot Dinosaur

Natural selection theory for paper dinosaurs

Dave the Dot to Dot Dinosaur is back and still trying to figure out his new surroundings.

I’d forgotten how much I missed him, until I started to draw him again for this cartoon.


Dave the Dot to Dot Dinosaur gets a shock


Dinosaur bones with a difference

Dinosaur fossils (Latin  fossus, meaning ‘having been dug up’) aren’t made of bone, they are made from rock (silica).

According to Wiki there are 6 ways of achieving this, but I’ll only describe the permineralization process. First, the dinosaur had to die and be covered up pretty much immediately (such as sinking in mud) before the scavengers found it. As time passes, more sediment covers the remains and the flesh starts to rot away, leaving only the bones which decay slower.  As they decay, groundwater carrying rich minerals seep into where the bone once was. Effectively it is a mineral replacement process with the replacing of ‘bone’ mineral with ‘rock’ mineral. Once the bone has all been replaced you have a perfect replica of the original bone, but now made from rock.

Thanks to Murphy, our beautiful lady golden retriever, for modelling for this cartoon.

I wonder how Dave is going to get himself out of this one?


Too much of a good thing?

Never, when it comes to Dave the dot to dot dinosaur!

If only Dave had one of those funky new photocopy cards which require you to log into the photocopier before printing, he wouldn’t be in this mess.
