Normal polarity
Explanation:
Earth's magnetic field used to be twice as strong 1.5 billion years ago as it is today and Earth's temperature other than what the geologists see from the 'normal' pattern. It has been noticed that some volcanic rocks were magnetized in opposite direction to the direction of the local Earth's field. It is clear that the Earth has experienced the normal polarity 1.5 years ago but at that time, the Earth's polarity was poorly understood.

There are multiple characteristic that all dinosaurs shared. Some of the synapomorphies include:
- Vertebrates; skeletons with back bones that surrounds a nerve cord.
- Amniotes; specially adapted for life on dry land.
- Diapsids; two holes located above and behind the eye sockets on each side of the skull.
- Archosaurs; antrobital ferestra, a hole between the nasal hole and the eye socket hole.
But still all of this doesn't separate them from all others, what is unique to them is that all of the 'true dinosaurs' were land dwellers.
