What was the largest ichthyosaur? The find has been tentatively identified as Temnodontosaurus trigonodon. These were a group of large ichthyosaurs, measuring up to 12 metres long, with different species adapting to eat a range of hard and soft prey.

why did dinosaurs become extinct and not other animals? – Similar Questions
how did the homo erectus go extinct?
erectus likely went extinct due to climate change,” Ciochon added. “H. erectus was found with a collection of animal fossils that lived in an open woodland environment similar to the environment in Africa where it evolved. The environment at Ngandong changed, and the open woodland was replaced by a rainforest.
what evidence explains dinosaurs extinction?
Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth’s climate that happened over millions of years.

The Ferber method, also known as “graduated extinction,” is an infant sleep training program developed by Richard Ferber. In a series of training sessions, parents leave their children alone for strictly-timed intervals, ignoring any protests and cries they might hear.

Cheetahs have faced extinction at least two times in the past after their populations were reduced, leading to inbreeding. Once again, cheetahs face extinction today, due in part to surviving the past threats of extinction.

What happened after the end-Triassic extinction?
The end-Triassic extinction particularly affected the ammonoids and conodonts, two groups that serve as important index fossils for assigning relative ages to various strata in the Triassic System of rocks. Indeed, the conodonts and many Triassic ceratitid ammonoids became extinct.

Are cheetahs in risk of extinction?
Cheetahs are known for their speed and are the fastest land animals on our earth! They once roamed much of Africa and Asia, but are now endangered. Their loss of habitat, lack of prey to feed on, and their vulnerability to humans, hunters, and poachers has increased their risk of becoming extinct.
What is the name of the extinction?
Scientists refer to the major extinction that wiped out nonavian dinosaurs as the K-T extinction, because it happened at the end of the Cretaceous period and the beginning of the Tertiary period.
