The connecting link between birds(Class Aves) and Mammals(Class Mammalia) is Archeopteryx
No dinosaurs were mammals, but reptiles. "dinosaur" means "terrible lizard." Though there may be a link between dinosaurs and modern birds.
Monotremes lay eggs, as do reptiles. Monotremes' limbs go outward (rather than downward) from their main body, which is also true for reptiles. Monotremes lack a corpus callosum (which placental mammals have), as do reptiles. Monotremes and reptiles both have cloacas, while placental mammals have separate openings for urination and defecation. This evidence all shows monotremes to be a link between reptiles and mammals, but we now think that monotremes just evolved from an earlier branching from the mammalian tree of lineage than the marsupials and placental mammals evolved from. Monotremes are not a link between reptiles and mammals.
The pelycosaurs are considered a link between mammals and reptiles because they exhibit features of both groups. They share characteristics with early mammals, such as differentiated teeth and possibly some aspects of their skull structure, while also possessing reptilian-like features including sprawling posture and lack of a secondary palate. This combination of traits positions them as transitional forms between the two groups in evolutionary history.
y euglena is called the connecting link between plants and animal
Yes, bats can be considered a connecting link between mammals and birds in the trend of evolution because they are unique in being the only mammal capable of sustained flight. This adaptation has led to similarities with birds in terms of wing structure and flight behavior, suggesting a convergence in evolutionary pathways between these two groups.
No. Fossil evidence indicates that platypuses have always existed more or less in their current form. Ancient platypuses were larger and had teeth, unlike modern platypuses, but platypuses do not provide any sort of evolutionary link between reptiles and mammals.
Capillaries.
A link is used for connecting two nodes while path is a source over which data travels.

Birds and reptiles.
Archaeopteryx - when discovered - was the missing link between the reptiles and birds. It was still unable of real flight and had teeth.
