A few of the many criteria for the classification of threatened species are a reduction in population size based on observation, a population size of less than ten thousand mature individuals, and a 10% probability that the species will go extinct within the next 100 years.
There were hundreds of dinosaur species, not just five. Perhaps you mean a broader classification criteria, like family, order, or phylum.
Ring species complicate classification because they show a gradual change in characteristics among neighboring populations that can lead to challenges in defining clear species boundaries. The continuous variation in traits can make it difficult to determine where one species ends and another begins, blurring traditional classification criteria. This phenomenon highlights the complexity of species concepts and the limitations of traditional classification systems.

they are a threatened species because people eat them
No they are not a threatened Species
no. threatened species are close but not yet there to being endangered.
Extinct means there are none of that species in the wild, threatened means the number of that species is declining, and endangered means there are only a few thousand of that species in the wild.

The finest level of classification for animals is species.
The classification system for at-risk species is based on how many animals of a particular species are believed to be alive. It ranges from extinct to least concern. Other rankings include near threatened, vulnerable, endangered and critically endangered.
A threatened species is likely to have a larger population and a broader distribution than an endangered species. While both classifications indicate that a species is at risk, threatened species are considered to be experiencing a decline but are not yet facing the immediate risk of extinction like endangered species. As a result, threatened species may have more opportunities for recovery if conservation efforts are implemented effectively.
Terms commonly used to describe a threatened condition include "vulnerable," "endangered," and "critically endangered." These terms often pertain to species at risk of extinction, as well as ecosystems facing significant threats. Additionally, "threatened" itself is a formal classification used in conservation contexts to indicate that a species or habitat is likely to become endangered if current trends continue.
