is attack on titan (shingeki no kyojin) episode 76 filler?

Hange Zoë and Floch discover the shattered wagon and Levi Ackermann's motionless body with a Titan nearby. A Jaegerist offers to shoot Levi, but Hange says he is already dead.

Skeptical, Floch asks to take a look himself, but before he can, the Titan begins sucking in steam. Wary, since this is not the way Titans normally die, the Jaegerists point their guns at the Titan and wait until it dissolves into a skeleton, revealing Zeke Jaeger in the remains of its belly.

As the Jaegerists stare in shock, Hange takes the opportunity to grab Levi and dive into the nearby river to escape.
