El Gallo Formation

El Gallo Formation is a rock formation in Baja California composed of alternating layers of mudstone and sandstone stacked together. These sedimentary layers reach about 1,150 meters in total thickness and contain numerous well-preserved fossils.

The formation developed during the Late Cretaceous period roughly 86 to 66 million years ago when this area was covered by ancient seas. The rock layers formed from sediments that accumulated over this vast span of geological time.

The formation draws paleontologists and geology students who study the fossils and examine how dinosaurs once lived in this region. This ongoing research helps reveal what ancient North American ecosystems were like.

Access to the formation follows marked research paths that allow people to examine the exposed rock layers up close. Visitors should wear sturdy footwear and prepare for rough terrain and desert conditions.

The formation holds fossilized dinosaur eggs that are remarkably well preserved, offering rare insight into how these creatures reproduced. These eggs make this location particularly valuable for paleontological study.
