The 24-hour day is not fixed but slowly stretching, and in the dinosaurs' time it was shorter: the Moon's pull is gently braking Earth's spin, so a day back then ran about 23.5 hours, and far shorter deeper in the past
Earth’s rotation is gradually decelerating as the Moon drifts further into space, fundamentally altering the length of our planet's day.
