Having a broad or wide jaw; the same meaning as eurygnathic.
From Greek 'eury-' (wide) and 'gnathous' (jawed), using the '-ous' adjectival suffix as an alternative to the '-ic' ending.
Scientists gave multiple names to the same trait—eurygnathic, eurygnathous—which is why reading old scientific papers can feel like learning a whole new language!
