Paleozoic

You are absolutely correct that over the time period that life has existed on earth in complex, multicellular, differentiated-tissue forms (the paleozoic through the cenozoic) co2 concentrations have been much higher than they have been recently. ❋ Unknown (2009)

As much as any destination, it is these isolated periods in untried hotel rooms, in paleozoic canyons, in disintegrating palaces and empty service-station restaurants that facilitate the underlying point of our journeys. ❋ Alain De Botton (2011)

But these refashioned Knicks are not very fun to watch, and nowhere near a lock as a playoff team, not even in a junk division where the sub-.500, paleozoic Celtics sit in second place. ❋ Jason Gay (2012)

It also lies on a Precambrian bedrock peneplain, with deep paleozoic sediments, but unlike the boulder-rich moraine of the archipelago, the moraines of Hudson Bay are boulder-poor, owing to softer rocks. ❋ Unknown (2008)

Unless you are involved in academic research CO2 levels in the paleozoic are irrelevant because so many other important variables affecting climate were different from today. ❋ Unknown (2006)

‘Waldheimia’ less embryonic, or more specialized; than the paleozoic ‘Spirifer’; or the existing ❋ Unknown (2007)

And I am not sure that arthropod sizes peaked in the paleozoic. ❋ Unknown (2007)

Add to that the fact that different species only exist in certain spans of time, such as dinosaurs in the mesozoic, or trilobites in the paleozoic. ❋ Unknown (2007)

I also knew the difference between the paleozoic and cretaceous periods. ❋ Ann Althouse (2007)

Geologically the Hajar and Musandem Mountains are comprised of paleozoic, metamorphic, and igneous rocks formed at the site of a mid-oceanic ridge in the Indian Ocean. ❋ Unknown (2007)

But then, on careful consideration of the facts, the objection arises that the stalk, calyx, and arms of the paleozoic Crinoid are exceedingly different from the corresponding organs of a larval ‘Comatula’; and it might with perfect justice be argued that ‘Actinocrinus’ and ❋ Unknown (2007)

But then again, this was way back in the paleozoic era; instead of saying "I do," Mr. DressADay grunted and handed me a haunch of wooly mammoth. ❋ Unknown (2006)

Stopped at a Precambrian-paleozoic reef formation, found some pretty interesting things, not really with fossils though. ❋ Andrew (2004)

If this is the case then how ever did we get out of the paleozoic period when CO2 concentrations started at 7000ppm. ❋ Unknown (2005)

Not content with being surly, bad-tempered, wanting to go and play in the paleozoic era, not seeing why they had to have the gravity on the whole time and shouting at the sun to stop following her, Random had also used his carving knife to dig up stones to throw at the pikka birds for looking at her like that. ❋ Adams, Douglas, 1952- (1992)

Arthur didn't even know if Lamuella had had a paleozoic era. ❋ Adams, Douglas, 1952- (1992)

He will also include in his studies certain paleozoic formations which are immediately connected with the crystalline schists and involved in their orographic structure. ❋ Various (N/A)

Louis Agassiz, who, on the other hand, continued up to his death in opposition to the entire doctrine of descent, made the idea of _types_ the principle of his whole classification, and said: "Man is the purpose toward which the whole animal creation tends from the first appearance of the first paleozoic fish." ❋ Rudolf Schmid (N/A)
