Lågt havnivå kan òg ha medverka til ekstreme temperaturar. Med stor <a href="/wiki/Spesifikk_varmekapasitet" title="Spesifikk varmekapasitet">spesifikk varmekapasitet</a> fungerer vatn som eit temperaturstabiliserande varmeresrovar og landområda nær store vassmassar, særleg nær hava, får ikkje så store temperatursvingingar.

Dette ser ein igjen i berglaga frå denne tida som består av <a href="/w/index.php?title=Raude_lag&action=edit&redlink=1" class="new" title="Raude lag (sida finst ikkje)">raude lag</a> og <a href="/wiki/Evaporitt" title="Evaporitt">evaporittar</a> som <a href="/wiki/Salt" title="Salt">salt</a>. </p><p>Havnivå byrja å stige i juratida, som truleg kom av <a href="/wiki/Havbotnsspreiing" class="mw-redirect" title="Havbotnsspreiing">havbotnsspreiing</a>. Danninga av ny skorpe under overflata flytta havvatnet så mykje som 200 meter høgare enn i dag og kystområda vart lagt under vatn. I tillegg byrja Pangea å dele seg opp i mindre bitar slik at større landområde kom i kontakt med havet ved at <a href="/wiki/Tethyshavet" title="Tethyshavet">Tethyshavet</a> oppstod. Temperaturane heldt fram å auke før dei stabiliserte seg. <a href="/wiki/Luftfukt" class="mw-redirect" title="Luftfukt">Luftfukta</a> auka òg sidan fleire landområde kom nær havet og ørkenane trekte seg tilbake. </p><p>Klimaet i krittida er meir usikkert og omstridt.

Middeltemperaturen var òg om lag 10 °C høgare enn i dag. Faktisk kan havområde nær ekvator i mellomkrit vore altfor varme (kanskje 30 °C i djuphavet) til å innehalde liv og landområda nær ekvator kan ha vore ørkenområde trass i nærleiken til havet. <a href="/wiki/Oksygen" title="Oksygen">Oksygentilførselen</a> til djuphavet kan òg ha stoppa opp. På grunn av dette samla det seg store mengder organisk stoff sidan det ikkje kunne rotne og vart til slutt <a href="/wiki/Avsetting" class="mw-redirect" title="Avsetting">avsett</a> som <a href="/w/index.php?title=Svartskifer&action=edit&redlink=1" class="new" title="Svartskifer (sida finst ikkje)">svartskifer</a>. </p><p>Ikkje all tilgjengeleg informasjon støttar desse hypotesane.

Krit-tertiær-utryddinga stogga denne trenden. Dei store archosaurane døydde ut, medan fuglar og pattedyr slo seg opp, og danna grunnlaget for dagens dyreliv. </p> <div class="mw-heading mw-heading2"><h2 id="Kjelder">Kjelder</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Mesozoikum&veaction=edit&section=5" title="Endre bolk: Kjelder" class="mw-editsection-visualeditor"><span>endre</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Mesozoikum&action=edit&section=5" title="Rediger kildekoden til seksjonen Kjelder"><span>endre wikiteksten</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="references-small"> <ul><li><i>Denne artikkelen bygger på «<a href="https://en.wikipedia.org/wiki/" class="extiw" title="en:">en:</a>» frå <a href="https://en.wikipedia.org/wiki/Main_Page" class="extiw" title="en:Main Page">Wikipedia på engelsk</a>, den 23. august 2008.</i> <ul><li><i><a href="https://en.wikipedia.org/wiki/Main_Page" class="extiw" title="en:Main Page">Wikipedia på engelsk</a> oppgav desse kjeldene:</i></li></ul></li> <li><i>British Mesozoikum Fossils</i>, 1983, The Natural History Museum, London.</li></ul> <style data-mw-deduplicate="TemplateStyles:r3318915">.mw-parser-output .reflist{font-size:90%;margin-bottom:0.5em;list-style-type:decimal}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text">Stanley, Steven M. <i>Earth System History</i>.
