What does the name Xenotarsosaurus literally mean based on its fossil discovery?
Answer
Strange ankle lizard
The name *Xenotarsosaurus* directly translates to 'strange ankle lizard.' This naming convention is a direct reflection of the unique morphological feature discovered in its fossil remains, specifically the highly unusual configuration and articulation of its tarsal bones, or ankle bones. This characteristic was significant enough to define the entire genus, setting it apart taxonomically from other theropods discovered in the region. The structure implied specific adaptations related to locomotion or weight bearing that differed notably from its contemporaries, making the 'strange ankle' component the primary identifier for this Patagonian dinosaur.
