Which was earlier the Triassic or Jurassic Period?
The Triassic Period occurred before the Jurassic Period. The Triassic Period lasted from about 251 million to 201 million years ago, while the Jurassic Period followed, lasting from about 201 million to 145 million years ago.
How many years ago was 1-1.8 million years ago?
1-1.8 million years ago was approximately 0.2-0.8 million years ago.
What is the length in millions of years of the Tertiary period?
The answer is 63.2 million years. Since the Tertiary Period began 65 million years ago and then stoped 1.8 million years ago you have to subtract the 1.8 million from 65 million to get the actual lenght of time.
How long ago was the Jurassic era?
It lasted 64 million years.

What happened during the silurain period?
If by "Silurain" you actually mean Silurian , it refers a time period ranging From 425 million to 405 million years ago; this period extends from the end of the Ordovician ( From 500 million to 425 million years ago; conodonts and ostracods and algae and seaweeds) Period, to the beginning of the Devonian Period ( From 405 million to 345 million years ago; preponderance of fishes and appearance of amphibians and ammonitesthe Silurian period refers to when, the first air-breathing animals arrivedthe Silurian period is also divided into subdivisionsLlandoverythis epoch lasted from 443.7 ± 1.5 million years ago to 428.2 ± 2.3 million years ago, and is further subdivided into three stages:the Rhuddanian, lasting until 439 million years ago,the Aeronian, lasting to 436 million years ago, and the Telychian.The epoch is named for the town of Llandovery in Carmarthenshire, Wales.WenlockThe Wenlock, which lasted from 428.2 ± 2.3 million years ago to 422.9 ± 2.5 million years ago, is subdivided into: the Sheinwoodian (to 426.2 million years ago) and,The Homerian ages.It is named after the Wenlock Edge in Shropshire, England. During the Wenlock, the oldest known tracheophytes of the genus Cooksonia, appear.LudlowThe Ludlow, lasting from 422.9 ± 2.5 million years ago to 418.7 ± 2.7 million years ago, comprises the Gorstian stage, lasting until 421.3 million years ago, and the Ludfordian stage. It is named for the town of Ludlow in Shropshire, England.PřídolíThe Pridoli, lasting from 418.7 ± 2.7 million years ago to 416 ± 2.8 million years ago, is the final and shortest epoch of the Silurian.It is named for the town of Přídolí in the Czech Republic.The Silurian system was first identified by British geologist: Sir Roderick Impey MurchisonReferencesMikulic, DG, DEG Briggs, and J Kluessendorf. 1985.
