open-in-new
<p>The Fram Formation is an <a href="/facts/Devonian/nWgakqzk">Upper Devonian</a> (<a href="/facts/Frasnian/A20Pj5QJ">Frasnian</a>) sequence of rock strata on <a href="/facts/Ellesmere_Island/mtWoFsE2">Ellesmere Island</a> that came into prominence in 2006 with the discovery in its rocks of examples of the <a href="/facts/Transitional_fossil/ov9o5s9l">transitional fossil</a>, <i><a href="/facts/Tiktaalik/Dc3DWglv">Tiktaalik</a></i>, a <a href="/facts/Sarcopterygian/7Glajr07">sarcopterygian</a> or lobe-finned fish showing many <a href="/facts/Tetrapod/vWpAxzAW">tetrapod</a> characteristics. Fossils of <i><a href="/facts/Laccognathus_embryi/2flJvhaU">Laccognathus embryi</a></i>, a <a href="/facts/Porolepiform/d8r3f8M9">porolepiform</a> lobe-finned fish, and <i><a href="/facts/Qikiqtania/Rjy8AXF9">Qikiqtania</a></i>, a close relative of <i>Tiktaalik</i>, were also found in the formation. The Fram Formation is a Middle to Upper Devonian clastic wedge forming an extensive continental facies consisting of sediments derived from deposits laid down in <a href="/facts/Braided_stream/f3vSC2za">braided stream</a> systems that formed some 375 million years ago, at a time when the <a href="/facts/North_America/djNjCQIl">North American</a> <a href="/facts/Craton/fSuY37IC">craton</a> ("<a href="/facts/Laurentia/G54C2qc3">Laurentia</a>") was straddling the equator. </p>
