The condition of having deep alveoli is known as thecodont, and is present throughout Archosauria, including dinosaurs. Most squamates , on the other hand, show the pleurodont condition, where the teeth are fused to the inner sides of the jaw bones, or the acrodont dentition , in which the teeth are fused to the top of the jaw bones without ...

An adult bee hummingbird, the smallest known dinosaur. The smallest dinosaur known is the bee hummingbird, [158] with a length of only 5 centimeters (2.0 in) and mass of around 1.8 g (0.063 oz). [159] The smallest known non-avialan dinosaurs were about the size of pigeons and were those theropods most closely related to birds. [160]
