Causes of dinosaur extinction: 1. Species struggle; 2. Acid rain led to the extinction of dinosaurs; 3. Continental drift; 4. Geomagnetic changes; 5. Gender imbalance.

Dinosaur is a kind of creature in ancient China, which has become extinct at present, but many dinosaur fossils have been found in archaeology, which provides a lot of basis for scientists to study.

Details

01

Species struggles led to the extinction of dinosaurs: At the end of the Dinosaur Age, the first small mammals appeared, which were rodent carnivores that probably fed on dinosaur eggs. Due to the lack of natural enemies of this small animal, more and more, eventually eating all the dinosaur eggs, resulting in the extinction of the dinosaurs.

02

Acid rain led to the extinction of dinosaurs: At the end of the Cretaceous period, there may have been strong acid rain, which dissolved trace elements including strontium in the soil. Dinosaurs directly or indirectly ingested strontium through drinking water and food, resulting in acute or chronic poisoning. The last batch died.

03

Continental drift: Geological studies have proved that there was only one continent on the earth when dinosaurs lived, namely the “pan-ancient land”. Due to changes in the crust, this continent experienced a large division and drift in the Jurassic, which eventually led to changes in the environment and climate, and the dinosaurs became extinct.

04

Geomagnetic changes: Modern biology has proved that the death of some organisms is related to the magnetic field. Organisms that are sensitive to the magnetic field may become extinct when the Earth’s magnetic field changes. Scientists concluded that the extinction of dinosaurs may be related to changes in the Earth’s magnetic field.

05

Gender Imbalance: due to the cold weather, most of the hatchlings are male dinosaurs, which makes the ratio of male to female in the dinosaur world serious imbalance, as the gradual decline of female dinosaurs, the dinosaur family also went to the end.
