Explanation/info: [link]

Those are based on Lambeosaurus and Lambea (Ambea) was the first protype name. At first I wanted to do 2 fossils to have a set. One fossil pokemon would have been a Rock/Grass Sp. Defensive type with high Sp. Attack, another one would have been either Rock/Fire or Rock/Electric or Rock/Ice. But I didn't have much time to think about nice ancient animals to use as a base so I skipped the idea of the fossil set.

In last minute Lambea changed into Rock/Electric type. The eyes are kinda inspired by Vaporeon. I also tried put a geometrical shape (because newer pokemon are more geometrical while older have more organic look) in the design, Glameow was in my mind.

The idea is that it charges electricity with its tail and horn, it can discharge too much amount of electricity with it's arms (kinda like Raichu's tail). The arms are used to defense as well.

Evolution was made later. Not much to say here, you can see sketches here: [link]
