In the past years, in China they have discovered small dinosaurs with what looks like feathers
Hello Jean-Pierre; Let me rephrase Kholhring's comment a bit.
It was the non-avian dinosaurs that went extinct at the end Cretaceous. So, dinosarians remain a highly diverse taxon today. There are interesting questions about the dynamics of the extinction event that winnowed this one group. Best regards, Jim Des Lauriers
Taking for granted that birds in modern sense evolved from feathered Theropod dinosaurs during Jurassic Period, it is perfectly reasonable to conclude that birds are the only surviving dinosaurs.
But we can not say they are the last descendants because we never can predict the future of evolution, when or would birds give rise to another group of vertebrates? But if the question is meant to imply "so far". The answer is most definitely yes - so far.

Não, aves não são descendentes, são os próprios dinossauros...
Are these species related to dinosaurs?
Birds, crocodiles, sea turtles, sharks, crabs?
Hello Chia-Lin; To illustrate the degree of relatedness you should look at a phylogenetic diagram for Animalia. It would be difficult to say it in words. The first four in your list are more closely related to each other than they are to crabs. The first three are more closely related to each other than they are to sharks. There is probably more than one opinion about how closely related the first three are to each other. .... Look at a phylogeny for animals. Best regards, Jim Des Lauriers
