''Utrechtiaceae'' is an extinct family of trees related to modern conifers. 〔 (GBIF ) 〕 This family dates back to the late Carboniferous and early Permian. 〔 ( Voltziales (palaeos.org) )〕 ==Description== They were forest trees with almost horizontal standing leafy lateral shoots and with vertical tribes.They were generally small trees. 〔 At least with ''Utrechtia piniformis'' the side shoots are in whorls. 〔(Early Conifers ) 〕 Like other ''Voltzialean'' plants they had compact ovulate cones bearing bilateral bract-scale complexes. The leaves are scale-like, arranged spirally and only a few millimeters long.
