Period before Triassic?

The Triassic Period.

permian period

The Permian.

it was the triassic period 245 to 208 million years ago

Dinosaurs died at the very end of the Cretaceous period, which was from about 65 to 145 million years ago. The Jurassic period was before the Cretaceous period and was the period between 145 to 200 million years ago. The Triassic period was before the Jurassic period, and was the period between 200 million to 251 million years ago.

Carboniferous Silurian Ordovician Devonian Cambrian Pre Cambrian

The Triassic Period(251-199Ma) (the 1st period of the Mesozoic Era) preceded the Jurassic Period (199 - 145Ma).

Yes. all the PROSAUROPODS lived in the triassic period. PRO means before, SAUROPOD means long necked dinosaurs that lived in the JURASSIC and CRETACEOUS. PROSAUROPODS, on the other hand, lived in the TRIASSIC.

yes the first dinos appeared 230mya during the late triassic period

Just before the beginning of the Triassic (the CT boundary).

Panthalassa means "all seas." It was the all the world's oceans that surrounded Pangaea before the continental drift occurred in the triassic period.

the first dinos appeared 230mya during the late triassic period so it was well before the dinos time : )

The first mammals appeared in the Triassic Period of the Mesozoic Era, when dinosaurs had already been present for at least 9 million years.

The Permian period extends from 298.9 to 252.17 million years ago. it followed the Paleozoic period and came before the Triassic period. The climate at the time was very dry thanks to the destruction of rainforests. At the beginning of the Permian period, the Earth was still very cold but gradually warmed throughout the years.

None. The scorpion is an arthropod, and they existed long before the dinosaurs. Scorpions are anthorpods , they did not evolved from dinosaurs. They existed long before dinosaurs evolved. Its believed that scorpions existed in the Carboniferous Period (430 million years ago). Dinosaurs existed from the Triassic Period (230 million years ago) to the Cretaceous Period (65 million years ago).

The Jurassic period took place before the Cretaceous era and after the Triassic era. It started around 199 million years ago and ended about 44 millions years later. (145 million years ago if you can't do the maths).

Dinosaurs dominated chordate life on Earth for about 160 million years before their sudden extinction. Their dominion lasted from the Triassic Period to the end of the Cretaceous.

Yes. Mammals evolved in the late Triassic period about 230 million years ago while bird did not appear until the end of the Jurassic about 150 million years ago.

Yes, the first ammonites lived during the Devonian Period. This was about 370 million years ago. The Devonian Period was a part of the Paleozoic Era. Dinosaurs did not appear until the Triassic, approximately 230 million years ago. HTH, Dr. C.

Animals that are definitely turtles are found from the later Jurassic period, with some almost-turtles like Proganochys found in the late Triassic. The first dinosaurs are found in the early Triassic. So far, fossil evidence suggests that turtle-like possible ancestors with partial shells predate dinosaurs, but dinosaurs predate true turtles.

before your period

If we are picky about which organisms count as true mammals, then mammals first came into existence in the early Jurassic. Mammal-like organisms, which had been becoming more and more like modern mammals, had existed before. Cynodonts, an early ancestor of mammals, arose before the Triassic, in the Permian.

before

conception occurs appr 2 weeks after ur last period not before because if you got pregnant before your period your period would not come on conception occurs appr 2 weeks after ur last period not before because if you got pregnant before your period your period would not come on

Yes, ovulation comes before a period, so a woman will ovulate before her very first period, before her first period post-pregnancy, etc.

Parenthesis go before the period. The period signals the end of the sentence.

Mammals came before birds. The first mammals lived in the Triassic and the first birds lived in the Jurassic.

The earliest direct evidence for true mammalian life lies in a single fossilized brain case, found in China and described by Zhe-Xi Luo and Ai-Lin Sun in the 2001 issue of Science. The find, named Hadrocodium wui, dates to around 195 million years ago, placing the origin of true mammals sometime before the early Jurassic Period and perhaps even the late Triassic Period.

No if you have not had a period before but yes if you have had a period before. As soon as a woman has had her first period she can get pregnant.

Yes, about 2 days before I get my period I get VERY dizzy. Yes, about 2 days before I get my period I get VERY dizzy.

The Pax Romana was the period before christ.

No the Cambrian Period came before the Jurassic Period.Periods in the Paleozoic Era (542 - 251 Ma) and the Mesozoic Era (251 - 65.5 Ma)Cambrian (542 - 488.3 Ma)Ordivician (488.3 - 443.7 Ma)Silurian (443.7 - 416 Ma)Devonian (416 - 359.2 Ma)Carboniferous (359.2 - 299 Ma)Permian (299 - 251 Ma)Triassic (251 - 199.6 Ma)Jurrasic (199.6 - 145.5 Ma)Cretaceous (145.5 - 65.5 Ma)

the period is teritary the period after dinosaurs

You must have ALL the period signs before a period.

The Cretaceous Period was after the Jurassic Period.

Usually you get PMS symptoms about a week before your period is due to start.

The main dinosaur periods were the Triassic, Jurassic and Cretaceous periods. they were in the mesozoic era. there were other periods before dinosaurs like the carboniferous.

do quotation mark go before or after period

It is possible but highly unlikely. When you have your period it is to flush out your system, it it not? When you get pregant right before your period (Before the sperm reaches the egg) the period flushes it out.
