'''Squatiniformes''' is an order of sharks belonging to [[Squalomorphi]]. It contains only a single living genus ''[[Squatina]]'', commonly known as angelsharks. The oldest genus of the order, ''[[Pseudorhina]]'' is known from the [[Late Jurassic]] of Europe.<ref name=":1">{{Cite journal |last1=Klug |first1=Stefanie |last2=Kriwet |first2=Jürgen |date=2013 |title=Node age estimations and the origin of angel sharks, Squatiniformes (Neoselachii, Squalomorphii) |journal=Journal of Systematic Palaeontology |language=en |volume=11 |issue=1 |pages=91–110 |doi=10.1080/14772019.2012.674066 |bibcode=2013JSPal..11...91K |issn=1477-2019}}</ref> Three other genera, ''[[Cretasquatina]]'', ''[[Cretascyllium]]'' and ''[[Parasquatina]]'' are known from [[Cretaceous]] fossils from North America and Europe,<ref name=":0">{{Cite journal |last1=Maisey |first1=John G. |last2=Ehret |first2=Dana J. |last3=Denton |first3=John S.S. |date=2020-06-16 |title=A New Genus of Late Cretaceous Angel Shark (Elasmobranchii; Squatinidae), with Comments on Squatinid Phylogeny |url=https://bioone.org/journals/american-museum-novitates/volume-2020/issue-3954/3954.1/A-New-Genus-of-Late-Cretaceous-Angel-Shark-Elasmobranchii-Squatinidae/10.1206/3954.1.full |journal=American Museum Novitates |issue=3954 |pages=1–29 |doi=10.1206/3954.1 |s2cid=219700378 |issn=0003-0082}}</ref><ref>{{Cite journal |last1=Guinot |first1=Guillaume |last2=Underwood |first2=Charlie J. |last3=Cappetta |first3=Henri |last4=Ward |first4=David J. |date=2012-05-11 |title=Squatiniformes (Chondrichthyes, Neoselachii) from the Late Cretaceous of southern England and northern France with redescription of the holotype of Squatina cranei Woodward, 1888 |journal=Palaeontology |language=en |volume=55 |issue=3 |pages=529–551 |doi=10.1111/j.1475-4983.2012.01140.x |bibcode=2012Palgy..55..529G |s2cid=129829100 |issn=0031-0239}}</ref> though the placement of ''Parasquatina'' in the order has been questioned.<ref name=":1" /> All living and extinct members of the order share a similar body morphology<ref name=":0" /> with a highly flattened body with enlarged pectoral and pelvic fins suggestive of a [[bottom-dwelling]] [[ambush predator]] ecology.<ref>{{Cite journal |last1=López-Romero |first1=Faviel A. |last2=Stumpf |first2=Sebastian |last3=Pfaff |first3=Cathrin |last4=Marramà |first4=Giuseppe |last5=Johanson |first5=Zerina |last6=Kriwet |first6=Jürgen |date=2020-07-28 |title=Evolutionary trends of the conserved neurocranium shape in angel sharks (Squatiniformes, Elasmobranchii) |journal=Scientific Reports |language=en |volume=10 |issue=1 |page=12582 |doi=10.1038/s41598-020-69525-7 |issn=2045-2322 |pmc=7387474 |pmid=32724124|bibcode=2020NatSR..1012582L }}</ref> Teeth have been assigned to the modern genus from the Late Jurassic onwards, but the actual genus assignment of many of these species is unclear.<ref name=":0" /> The earliest records that can be assigned with confidence to the modern genus are known from the Early Cretaceous ([[Aptian]]) of England.<ref name=":1" />
