It was said that in fights, the loudest roar wins. This is not backed up by any actual evidence.
In Walking With... series
The fact above was developed in the 3rd episode of WWD, where one lone Eustreptospondylus got snatched by a Liopleurodon. Later, two other Eustreptospondylus fight over a dead turtle. Three more attack and devour some Rhamphorhynchus. A group of Eustreptospondylus that survive a storm eat a stranded Liopleurodon caught by the storm.
Appearances in Other Media
In the book Fire and Water a Eustreptospondylus comes through an Anomaly in a South African Wildlife reserve and attacks many of its animals. It was killed in a battle with a Postosuchus.
