Trilobites, amphibians, and many other species of animals became extinct in the Permian-Triassic extinction. This event happened over 250 million years ago.
Trilobites
Trilobites first appeared in the Cambrian Period around 521 million years ago, while fish began to emerge around 480 million years ago. This evolutionary timeline suggests that trilobites appeared earlier than fish in Earth's geological history.
Ammonites appeared during the Devonian period, around 400 million years ago, while trilobites first appeared during the Cambrian period, approximately 540 million years ago. Therefore, ammonites came into existence after trilobites.
Trilobites were associated with the Paleozoic era, from the Cambrian to the Permian.

There is no period of time found called the Golden Age of Novel. There is the Golden, Silver, Bronze, and Heroic Ages.
Trilobites were warm blooded creatures that lived in the ocean from the cambrian period all the way until they were wiped out in in the permian period.
Chandra Gupta Maurya's period is called as Golden Age of Guptas.
Ballet. I do not believe Ballet is correct. Yet it may depend on what area within the romantic period you are referring to. If you are asking in regards to music the Romantic period is sometimes called "The Golden Age of the Piano." The piano was easily the most popular keyboard instrument of the time!
We sometimes call 50 years 5 decades, but half a centuryis more common.
No, trilobites are extinct marine arthropods that lived from the early Cambrian period to the end of the Permian period, around 520 to 250 million years ago. There are no living trilobites today.
Haikouichthys and Myllokunmingia were two vertebrates in the Cambrian Period
The trilobites went extinct during the mass extinction at the end of the Permian period.
