NHMUK A5430 was collected from Bed R6 of the Røsnæs Clay Formation of Ølst, Denmark (Harrison, 1984). Bed R6 is the uppermost division of the Røsnæs Clay Formation, and is overlain by Bed L1 of the Lillebælt Clay Formation (Heilmann-Clausen et al. 1985). Magnetostratigraphic work (Heilmann-Clausen et al., 2010) demonstrates that Bed L2 of the Lillebælt Clay spans part of Chron 22r, which constrains the age of the base of the Lillebælt Clay to >49Ma. Thiede et al. (1980) assigned the upper calcareous beds of the Røsnæs Clay Formation, including R5 and R6 to nannoplankton biozones NP11 and NP12. Biostratigraphy supports correlation of the Røsnæs Clay Formation to the European mammal reference biozone MP8 (Mlíkovsky, 1996), which suggests an age >50Ma (Gradstein et al., 2004). A conservative minimum age of 51Ma is proposed, based specifically on the estimated age of the upper boundary of NP12, which is dated to 51Ma (Gradstein et al. 2012).

Phylogenetic analysis of morphological data (Mayr, 2003, 2005c) and combined morphological and molecular data (Ksepka et al., 2013) places Scaniacypselus wardi closer to Apodidae than to Hemiprocnidae.
