Minmi was a small, heavily armoured ankylosaur that lived during the Early Cretaceous period, between 132.6 and 121.4 million years ago. This fascinating dinosaur roamed the ancient landscapes of what is now Queensland, Australia, making it one of the most completely known armoured dinosaurs from the Southern Hemisphere.
Measuring approximately 3 metres in length and standing about 80 centimetres tall at the hip, Minmi was considerably smaller than many of its ankylosaur relatives. Despite its modest size, weighing around 300 kilograms, it was built like a living tank with extensive bony armour covering its back, sides, and even its belly - a unique feature among ankylosaurs. Its body was low-slung and broad, supported by four sturdy legs that allowed it to move at speeds of up to 15 kilometres per hour when necessary.
As a herbivore, Minmi used its small, leaf-shaped teeth to process tough plant material including ferns, cycads, and early flowering plants that grew in the warm, humid climate of Cretaceous Australia. Its digestive system was highly efficient, with fossilised stomach contents revealing that it could break down fibrous vegetation effectively.
What makes Minmi particularly special is the exceptional preservation of its fossils, which have provided paleontologists with unprecedented insights into ankylosaur anatomy and behaviour, helping us understand how these armoured giants lived and survived in prehistoric Australia.
Minmi was distinguished by its comprehensive armour plating that uniquely extended to its belly, unlike other ankylosaurs. It had a relatively small head with a narrow snout and small teeth, plus distinctive rows of bony scutes and spikes running along its back and sides.
Minmi likely lived in small groups, browsing on low-growing vegetation in forested areas. When threatened, it would have relied on its extensive armour for protection rather than speed, possibly crouching down to protect its less-armoured underside, though its belly armour provided additional defence.
Minmi has appeared in several dinosaur documentaries and children's books about Australian prehistoric life, though it's less well-known in mainstream media than larger armoured dinosaurs.
Minmi was first described by Alan Bartholomai in 1964. The original fossils were discovered at Roma, Queensland, Australia.
