A now-dry barrier reef, located in present-day [[Kimberley (Western Australia)|Kimberley Basin]] of northwest [[Australia]], once extended {{cvt|350|km}}, fringing a Devonian continent.<ref>{{cite journal |last1=Tyler |first1=Ian M. |last2=Hocking |first2=Roger M. |last3=Haines |first3=Peter W. |title=Geological evolution of the Kimberley region of Western Australia |journal=Episodes |date=1 March 2012 |volume=35 |issue=1 |pages=298–306 |doi=10.18814/epiiugs/2012/v35i1/029|doi-access=free }}</ref> Reefs are generally built by various [[carbonate]]-secreting organisms that can erect wave-resistant structures near sea level. Although modern reefs are constructed mainly by corals and calcareous [[algae]], Devonian reefs were either microbial reefs built up mostly by [[autotrophic]] [[cyanobacteria]] or coral-stromatoporoid reefs built up by coral-like [[Stromatoporoidea|stromatoporoids]] and tabulate and [[Rugosa|rugose corals]]. Microbial reefs dominated under the warmer conditions of the early and late Devonian, while coral-stromatoporoid reefs dominated during the cooler middle Devonian.<ref>{{cite journal |last1=Joachimski |first1=M.M. |last2=Breisig |first2=S. |last3=Buggisch |first3=W. |last4=Talent |first4=J.A. |last5=Mawson |first5=R. |last6=Gereke |first6=M. |last7=Morrow |first7=J.R. |last8=Day |first8=J. |last9=Weddige |first9=K. |title=Devonian climate and reef evolution: Insights from oxygen isotopes in apatite |journal=Earth and Planetary Science Letters |date=July 2009 |volume=284 |issue=3–4 |pages=599–609 |doi=10.1016/j.epsl.2009.05.028|bibcode=2009E&PSL.284..599J }}</ref>
