TF Primordial Transformers

I was thinking of old life forms on this planet; how we have Trilobites and such small creatures before large dinosaurs came around and then modern mammals and large whales and such. And it hit me, why would Cybertron be any different? So with that in mind; I introduce to you my concepts of Primordial Transformer animals.

Mechanical Trilobite that can maybe turn into a shell or rock to hide from prey.
And a Mechanical pmeno...uh cant remember but will type it up as soon as I know

I dearly hope that this is somewhat like what the people over at hasbro/idw are thinking
