Haootia quadriformis was described from the lower Fermeuse Formation of the Bonavista Peninsula of Newfoundland (approx. 560 Ma) and its numerous regularly aligned impressions were interpreted as evidence of muscular tissue ([1, figs 1a and 3b]). Consequently, this fossil could represent the earliest preservation of metazoan musculature in the geological record.FAPESP (grant no. 2010/07362-7 to L.S.M., grant no. 2011/50242-5 to A.C.M.)CNPq (grant nos 142270/2010-5 and 165066/2014-8 to L.S.M., grant nos 562143/2010-6 and 305805/2013-4 to A.C.M.)CAPES/PDSE (grant no. 16499/12-3 to L.S.M.).NPBioMar, US
