This question is about G1 canon.
The Transformers are called "Cybertronians", and they all have to have been created by the Quintessons, Primus, or Unicron. Cybertronians can make Cybertronians; Megatron said the Decepticons built the Constructicons, and it is revealed they did this on Cybertron in a later episode. They are in every way similar to other Cybertronians, other than being the first Combiner team.
The Dinobots are different. First, they were built by Wheeljack (not Shockwave) on Earth, so they could be called "Earthlings ". And, as seen in "Desertion of the Dinobots", they could function without Cybertonium unlike the other Cybertronians, implying that they are chemically different entirely.
So, could they be called Cybertronians in terms of species, or would they be called some other scientific name?
