Its a bird

No, that's definitely a bat. See the mammalian ears? Besides, can't you see the Galliformes next to the bat? Galliformes wouldn't be shown twice.

I don't see the ears, also it is in the same spot as the bird upgrade is, so i doubt its anything else, but i will check on a test save just in case

So an image of a bat is shown where the bird trophy should be, if you haven't reached rank 23 in Mesozoic Valley yet? Now, since it's a trophy, it shouldn't be shown before reaching rank 23 at all, let alone with a bat image.

It's worth noting that unlike Galliformes, the bat shows even if you haven't reached rank 15, when the last (non-avian) reptile generator, the snake, is unlocked. So previously, I thought it was Galliformes. I also had a hypothesis that the bat was Neoaves, but Neoaves unlocks at rank 38.

I just reached rank 23, and it is the bird trophy. It's just that it's incorrectly shown as a bat.

The bird trophy unlocks at rank 23 thats a bird not bat
