Eared Rovett
The eared rovett is essentially an omnivorous version of the rovett (V. genikus). Though roughly identical in size, being 2 feet long and .8 feet tall at the hip, it has developed a few new characteristics: a slightly shortened snout for stronger biting and chewing, especially of tough polyphs; an opposable thumb for better grip; and a simple ear consisting of a tympanic membrane stretched over a depression in the lower jaw bone which allows it to better listen for prey or danger (angry terrasuchids) as well as hearing giving it a tactical advantage in intraspecific combat. It became an omnivore, thus its teeth are curved and serrated in a manner similar to the teeth of real-world troodontids.
Its omnivory developed as a result of individuals sometimes being unable to vomit after swallowing leaves, such as when the reflex failed or the irritants were so deep in the digestive system that they kept consuming leaves to no avail, causing those with enzymes that could break down these leaves being able to avoid impaction and survive; with little competition for polyph-eating niches further inland, this allowed them to eventually shed their leaf-vomit reflex and begin to consume polyph matter when competition made meat scarce. Its enzymes for digesting polyphs cause sugars from the polyphs to be converted to a small amount of alcohol during the process.
The eared rovett has similar mating practices to its ancestor. It lost its sexual dimorphism, as camouflage to avoid detection was more valuable than randomly being green; still, males fight over females in the spring, and after mating they stay together and the female lays 3-6 eggs in a nest she builds. The eggs take about 2 weeks to hatch, and the young are fed and taught to hunt by both parents until they are sub-adults and can go off to live on their own. They reach maturity in about a year, just in time for the next mating season.
Like its ancestor, the eared rovett lives in groups with loose territory and a hierarchy determined by non-lethal combat. Due to their ability to eat a wider variety of food, the lack of intraspecific competition has completely eliminated their ancestral territorial behavior, so the groups don't come into conflict and can overlap to an extreme level, sometimes as far as having individuals shared between the groups. They still battle over mates.
The eared rovett eats all the same muscals as its ancestor, but also eats polyphs such as P. callioptoma, P. plumosa, L. fernus, L. potensus, and P. ipsumsemenous. Like its ancestor, it uses its claws to grapple larger prey, but it will also use them to help it reach leaves in taller polyphs.
