I actually live in the UK but my parents live in Vietnam and my Mum sent me the attached picture today. They live in Hanoi in the north of the country, around the region of West Lake. They found it when taking the dog for a walk on a dried riverbed near their house. It's seasonally dry though so will be wet again whenever.
I'm no fish expert but am a huge fan of all wildlife and avid nature enthusiast... but I've never seen anything looking so like a dinosaur with the wide fan-like skull and the spines up the back, also are they bone spines under its chin? It's backward teeth look pretty mean too!
Do you know what type of fish this is?
