Finishing the Asteroid's Work?

It's well-established an asteroid strike in Mexico, about 66 million years ago, 'did for' the giant dinosaurs. Many smaller reptiles, however, continued to thrive. We often think that reptiles are 'inferior' to mammals. However, a reptile needs only a fraction of the food, required to maintain a Mammal of the same size. A paper in Nature, suggests that more than 20% of the planet's endemic reptiles are now facing extinction (https://www.theguardian.com/environment/2022/apr/27/one-in-five-reptiles-face-extinction-in-devastating-blow-to-biodiversity-aoe). The 1,800 currently-endangered reptile species, are mainly threatened by human-mediated habitat loss. So, what are called Anthropogenic effects, could finish the work of the asteroid. Disappearance of these reptiles would, however, have profound effects on ecosystems. Some of the endangered animals, for example, importantly consume copious quantities of insect pests.
