I would love to see these ones added in the game, and I think others interested in paleontology and such would find them interesting as well: Old reconstructions. the description could be something like:
When our scientist created this dinosaur they noticed an uncanny resemblance to older representations of dinosaurs, so they decided to keep the name as a hommage.
Victorian Iguanodon: could be a hybrid between Iguanodon and Moschops:
Victorian Hylaeosaurus: Altough the game doesn’t have a hylaeosaurus they could use another ankylosaurus.
