@Swampy Of course it's the one sign I took a photo of that came out blurry. I think I can make out Pelomedusa on the sign, but the word after that only has a few letters. They were also exhibited with Caiman Lizards if that helps - location wise.
@Ituri oh gosh you're right, even still got traces of the yellow spotting- Podocnemis unifilis it is.
