What does Claire use to trick the Baryonyx?

Her tank top

Claire’s pink tank top was saturated with her sweat. She quickly tore it off, leaving her top covered only by her dirty white bra. To doubly make sure the tank top was loaded with her scent, she rubbed the top all over her body. Her arms, armpits, forehead, head, neck, stomach, legs and even in between her legs. Now soaked to the brim with sweat, Claire bundled it into a ball and threw it hard down the right hallway. Quickly, she ran to the gap and crawled in. There was enough room inside for her to mauver around to face out the gap.

She managed to hide just in time to see the Baryonyx grind to a halt before the T-Junction. Claire sucked in a breath and held it as the Baryonyx sniffed the air, shifting its head back and forth between the right hallway and the gap she was inside of.
