Formation. Open, marshy mud flats. Size: WS unknown; BL ~1.3m (4.4ft); TL unknown<br />
Features: Mid-sized troodontids known from a single snout bone (maxilla). High, rounded<br />
snout characterized internally by extensive air-filled cavities <strong>and</strong> prominent, elongated<br />
openings. Tooth sockets square & separated by small walls of bone. Biology: The broad<br />

snout. Neck relatively long. Body long with very small wings & small wing claws. Legs<br />
