However, only a few papers have discussed this issue using a taphonomical approach. In addition, although <i>Scolicia</i> is commonly present in deep-sea and shelf ichnoassemblages, its record in slope deposits is scarce. Herein, variations in the preservation of <i>Scolicia</i> are discussed in slope and basin floor contexts from the Eocene Capdevila Formation, western Cuba. The studied specimens come from two outcrops located in the Artemisa and Pinar del Río regions. The burrows were assigned to <i>Scolicia prisca, Scolicia </i>isp. var. vertebralis, and <i>Scolicia </i>isp. var. laminites. The observed variations in the diagnostic features of <i>Scolicia</i> reflect the wide variation expected in burrows made by spatangoid echinoids. Furthermore, we demonstrated that <i>S. vertebralis </i>could be a preservational variant of <i>S. prisca </i>and that <i>S. prisca</i> could be produced as furrows by extant echinoids, and not necessarily represent eroded burrows. In the Artemisa section, <i>Scolicia</i> is associated with basin floor deposits in bathyal context and form part of the <i>Nereites</i> ichnofacies. In the Pinar de Río section, <i>Scolicia</i> occur in shallower slope deposits and is included in the impoverished <i>Cruziana</i> ichnofacies. Their presence in slope deposits could be due to different factors, such as the predominance of sandy substrates, high sedimentation rate, and good oxygenation, which also led to an absence of trace fossils of the <i>Zoophycos </i>ichnofacies, which is typical of slope settings.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Paleoecology and taphonomy of spatangoid echinoid-produced burrows (<i>Scolicia</i>) in slope and basin floor deposits from the Eocene of Cuba","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-03-17 01:37:34.728976","timezone_type":1,"timezone":"+01:00"},"AuthorKeywords":"trace fossils; <i>Scolicia</i> preservational variations; Capdevila Formation; early Eocene","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-03-10","DateCreate":"2025-03-10","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.26879/1271"},"refs":null,"anarec":{"AnaID":406012,"PubliDate":2025,"Pagination":"a4","XtraPublOfAnaID":null,"ISBN":null,"Volume":"28","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":275996,"SerRR":"Palaeontologia Electronica.
