Dinosaurs are technically:Group of answer choicesPseudosuchiansTherapsidsBirdsArchosaurs

To accurately classify dinosaurs, we can analyze the options provided:

1. Pseudosuchians: This is a clade that includes crocodilians and their relatives, which are not technically dinosaurs. Therefore, this option is incorrect.

2. Therapsids: These are a group of synapsids that are more closely related to mammals than to dinosaurs. Thus, this option is also incorrect.

3. Birds: Modern birds are indeed considered the direct descendants of theropod dinosaurs. However, while they are technically part of the dinosaur lineage, this option might mislead one into thinking all dinosaurs are birds.

4. Archosaurs: This group includes all dinosaurs, birds, and crocodilians. Thus, this option correctly classifies dinosaurs as it encompasses their entire lineage.

Summary

The correct answer that categorizes dinosaurs accurately is Archosaurs, as they represent a broader category that includes both dinosaurs and their closest relatives.
