Overall, I'm a bit bittersweet about the expo. I love paleo-themed events, but the quality and accuracy is very inequal. I'm not talking about colours (that's artistic liberty), it's more the Epidexipteryx which should never have ended up so outdated for example.
The signs aren't really helpful at understanding which animal you're looking at (a simple silhouette would have done the job!), instead we have what looks like placeholder ovals. A problem in production? There's also a sign for Anomalocaris, but I haven't seen any!
