Although originally described as a separate genus, Leipsanosaurus is now recognised as being the same animal as Struthiosaurus, making it one of Europe's smallest known ankylosaurs. This heavily armoured herbivore lived during the Late Cretaceous period, between 83.6 and 72.2 million years ago, roaming the ancient islands and coastal plains that would eventually become modern-day Romania and other parts of Europe.
Measuring just 2.5 metres in length and weighing around 350 kilograms, this ankylosaur was remarkably compact compared to its massive relatives found in North America and Asia. Its small size was likely an adaptation to island living, where limited resources favoured smaller body sizes. The dinosaur's back and sides were protected by rows of bony plates and spikes embedded in its skin, creating a formidable defensive barrier against predators.
As a herbivore, Leipsanosaurus spent its days browsing on low-growing plants, ferns, and cycads that flourished in the warm Cretaceous climate. Its small, leaf-shaped teeth were perfectly suited for cropping vegetation, whilst its robust build allowed it to push through dense undergrowth in search of food. The dinosaur's four sturdy legs supported its armoured body as it moved slowly but steadily through its forest habitat.
The discovery and subsequent reclassification of Leipsanosaurus highlights how palaeontology continues to evolve as new evidence emerges, helping scientists better understand the relationships between ancient creatures and refine our knowledge of prehistoric life.
Leipsanosaurus was characterised by its compact size and extensive bony armour plating covering its back and flanks. Its small stature, measuring only 2.5 metres long, made it one of Europe's tiniest armoured dinosaurs, with rows of defensive spikes and plates providing protection despite its diminutive size.
This ankylosaur likely lived a solitary lifestyle, slowly moving through dense vegetation whilst foraging for plants. When threatened by predators, it probably crouched down to protect its soft belly, relying on its heavily armoured back and potentially using its tail as a defensive weapon.
Leipsanosaurus was first described by Franz Baron Nopcsa in 1929. The original fossils were discovered at Transylvania, Romania.
