Liaoningosaurus - a semi-aquatic fish-eating ankylosaur?

[stargatedalek]

From what I've seen the authors don't make a particularly strong case against alternate taphonomic explanations for the presence of the fish in the specimen. I wonder if isotope analysis would be useful here?

Isotope analysis would only prove whether or not it was aquatic, not whether or not it was omnivorous.

I think the fragmentary nature of the fish is fairly conclusive. If the ankylosaur was also fragmentary one could make an argument this was a prey cash of sorts, or if the fish were more intact one could argue they may have been scavenging.

Very interesting...it's amazing what continues to turn up these days!
