Because the speed of Earth's rotation changes over time, a day in the age of dinosaurs was just 23 hours long.

"The reason is that the Moon is attempting to slow down the spin of the Earth. The Earth was spinning very much faster when the Moon was formed,"
Dr Rosemary Mardling
Back when the Moon was formed the length of an Earth day was a very brief two to three hours, and a much closer Moon was orbiting the Earth every five hours.
Did you know that? Some of the biggest plant eaters dinosaurs had to eat as much as a ton of food a day. This is similar to eating a bus-sized pile of vegetation every day.
It is also interesting that many people think dinosaurs were massive but dinosaurs were usually human sized or smaller. Scientists believe that the larger bones were just easier to be fossilized.
