If brainy dinosaurs such as Troodon evolved into a highly intelligent
creature, isn't it possible that along with tool making, some form of written
language could have developed?
If so, what kind of writing do you see having developed?
One idea I had would be a form of symbolic writing by means of scratch marks
left on soil [temporary], plant material [longer lasting], rock
[semi-permanent], utilizing the 3 claws on both hands.
A combination of vertical and angles slashes, producing 1, 2, or 3 lines,
either alone or mixed, representing an idea, warning, or notice.
||| |\ \\ / | /// etc.
I've seen some birds scratch-out marks in the soil with their feet [just one
foot used] that didn't look like just random scratching or acquiring food.
Some of the other birds would look at the marks made with some interest.
