Sorry for the wait, it's that i had a "percance" and didn't have the image ready since august.
The thing is, Jacadamia hadn't NAMED this short-lived species. I hope they're not closed lol.
The "dinojacashi 2020" comes from the fact that jacadamia himself retrospectively called them "dino jaca" one YEAR after they became obsolete. "jacashi" is one of his replies, as they resembled yoshis. "'20" is because that was the only year they were used. After that, they became obsolete by macamo the fluffernutter and passed onto the realm of oblivion.
