The insect attack has ended the dinosaur period

Maybe by the time the extinct dinosaurs had meteoric crashes or volcanic eruptions occurred, but there was a book that debated the most powerful creatures in the world that had been 'beaten'. collapsed ' by small insects, much weaker and even sick.

According to experts, an important factor that makes dinosaurs extinct may be the evolution and increase of insects; Especially, the danger is slow but powerful from newly emerging carriers. Evidence for this threat is still retained in most real animal details - many of the insects in amber were created at the time of the dinosaurs disappear.

George Poinar Jr. - Professor of zoology at Oregon State University, said: 'There are many problems around the hypothesis of the dinosaur extinction. They are thought to reduce the number and disappear about hundreds of thousands or even millions of years ago. That time frame is not only suitable for the time when meteorite crashes occurred, but the competition with insects caused disease to arise as well as the widespread development of flowering plants for a long time also matched. completely with what we know about the extinction of dinosaurs'.

The book ' What Bugged the Dinosaurs? Insects, Disease and Death in the Cretaceous ' (roughly translated as' What makes the dinosaurs uncomfortable? Insect, disease, or death of the Cretaceous era ') written by George and Roberta Poinar published in the sheet Priceton University Press has detailed the above viewpoint.

In the book, the authors argue that insects are a plausible and convincing answer to the slow and inevitable decline in the number of extinction of dinosaurs over thousands of years. This period is known as the ' KT Border ', which is the boundary between the Cretaceous and the Third Century around 65 million years ago. Although there is evidence of some catastrophic events, such as a meteorite or volcanic collision occurred at this time; however, they cannot give a complete explanation for the gradual reduction in dinosaur numbers. There are even species that existed for thousands of years after the ' KT Boundary '.

On the other hand, insects and diseases are much slower, but they may have ended the dinosaur era.

Poinar said: 'We do not think that the emergence of insects and the widespread spread of disease are the only factors that make dinosaurs extinct. Other horrifying geological events also contributed. But these events themselves cannot explain an entire process that lasts a long time, perhaps millions of years. While insects and diseases bring answers'.

Poinar and his wife, Roberta, spent a lot of time studying the types of plants and animals in amber to reconstruct the ecosystem of the previous year. They are also the authors of the book 'The Amber Forest: A Reconstruction of a Vanish World' (roughly translated as 'Amber Forest').

Amber is a type of semi-precious stone that serves as a natural embalmment with the original plant-like form. It has a unique ability: enveloping animals and small objects, maintaining them in nearly perfect three-dimensional shapes until millions of years later. This phenomenon is invaluable in scientific and ecological studies. Along with other things, it formed the scientific hypothesis for the Jurassic Park movie, and the hypothesis of ' dinosaur ' AND in the body of mosquitoes.

" During the end of the Cretaceous period, the relationship between insects, bacteria and infectious diseases has only just begun . We have found in an intestinal insect a white Cretaceous in amber a pathogen that causes leishmania - a disease in humans and reptiles to this day is still dangerous.In the body of another type of insect we discover that the factors causing malaria still affect birds and lizards today ".

'In dinosaurs, we found nematodes, trematodes and even protozoa causing dysentery as well as some other abdominal pain. The parasites in the gut have spread because insects often visit the landfill ".

According to Poinar, at the end of the century, the Cretaceous Earth was covered by a mild, warm climate along with a multitude of blood-sucking insects carrying leishmania, malaria, parasitic helminths, and virus-killing and other pathogens that cause persistent outbreaks one after another and gradually reduce the number of dinosaurs. Mosquitoes, mites, lice and fleas have tortured and made dinosaurs weak.

'The herds of isolated dinosaurs that were small were attacked many times; like the malaria epidemic in birds when it spread to Hawaii, many bees died. Over millions of years of evolution, mammals, birds and reptiles have formed some immunity to these diseases. But for the inhabitants of the Cretaceous, the above epidemics have just appeared and have tremendous destructive power. Vertebrate animals have little or no natural immunity to fight. The massive boom has caused local death and extinction '.

Scientists also believe that insects play an important role in altering the natural plant life on earth - the basic source of dinosaurs, whether they are herbivores, carnivores or omnivores. well. As the number of dinosaurs drops, their traditional food sources such as ferns, cycads, ginkgo trees and other conifer trees are replaced by flowering plants thanks to insect pollination. Flowering plants have proliferated and occupied space. Insects that spread plant diseases make large areas of trees destroyed. Insects are also competitors to supply formidable plant foods.

In the book the authors wrote: 'Insects have greatly influenced the entire ecosystem on the earth, forming evolution and causing extinction for land residents. The largest species - the dinosaurs - was locked up in the struggle of life and death with insects'.

The illness that arises, the loss of traditional food supplies, and the competition for food with plant pest insects has pushed the dinosaurs into a fragile, fragile state that they cannot overcome. Concerns weighed on them for thousands of years to end their work together with the impact of environmental changes, meteor, and devastating lava flows.
