Thitiwoot Sethapanichsakul grew up with a passion for dinosaurs that he's never shaken off. "I always told my high school teachers, 'I'm going to name a dinosaur and it's going to be from Thailand,'" he said. Today, Mr Sethapanichsakul is studying for a PhD in palaeontology at University College London — and is the co-lead author of a paper in Scientific Reports, describing the largest dinosaur ever discovered in South-East Asia.
