4A296657FFFCFFD1FC5DFF5793EA5E13.taxon	materials_examined	Holotype: TMP 2015.011. 0003, a complete fish preserved in right lateral view (Fig. 2). Paratype: TMP 2015.011. 0002, the anteroventral portion of a fish preserving the head and ventral body, missing the dorsal and caudal regions, preserved in right lateral view (Fig. 3). Type locality and age: Paskapoo Formation, Calgary, Alberta, Canada; late Palaeocene in age. Etymology: The specific epithet is for the Greek tany meaning long and oura meaning tail. The two previously described species are named for the shape of their dorsal and anal fins, but we name this third species for having a longer caudal peduncle than the others. Diagnosis: Differs from † J. symmetropterus and † J. triangulpterus by having 26 abdominal vertebrae (compared to 22 in † J. symmetropterus and 23 – 25 in † J. triangulpterus), falcate dorsal and anal fin (compared to rounded fin margins in † J. symmetropterus and triangular fins in † J. triangulpterus), 11 predorsal (supraneural) bones (compared to 16 in † J. triangulpterus and 18 in † J. symmetropterus). Further differs from † J. triangulpterus by having the pelvic fin positioned near to the centre point between the origins of the pectoral and anal fins rather than closer to the anal fin and having about four centra between the insertion of the first anal and dorsal fin pterygiophores, rather than 8 – 9 centra. Further differs from † J. symmetropterus by having the caudal peduncle longer than deep instead of deeper than long (unknown in † J. triangulpterus).	en	Murray, Alison M., Zelenitsky, Darla K., Brinkman, Donald B., Neuman, Andrew G.

4A296657FFF2FFDFFC1EFC1092625FB4.taxon	materials_examined	Type and only known species: † Lopadichthys colwellae sp. nov. Diagnosis: As for type and only known species. Derivation of name: The genus is named for the fish being disk or plate shaped, from the Greek lopas or lopados meaning a dish or plate, and the ending ichthys, Greek for fish. Gender is masculine.	en	Murray, Alison M., Zelenitsky, Darla K., Brinkman, Donald B., Neuman, Andrew G.

4A296657FFF2FFD9FC5DFB4F9552580A.taxon	materials_examined	Holotype: TMP 2015.011. 0001, a complete fish preserved in left lateral view (Fig. 7). Paratypes: TMP 2015.011. 0004, a complete fish preserved in left lateral view (Fig. 8), and TMP 2015.011. 0005, the posterior portion of a fish preserving the dorsal, anal and caudal fins and most of the body, but missing the head and anteroventral body, preserved in left lateral view (Fig. 9). Type locality and horizon: Paskapoo Formation, Calgary, Alberta, Canada; Palaeocene in age. Etymology: The specific epithet is in honour of Jane Colwell-Danis in recognition of her considerable contribution to vertebrate palaeontology in Alberta. She has published under the names Colwell, Danis and Colwell-Danis. Diagnosis: A deep-bodied osteoglossomorph fish with a head depth slightly greater than head length; two heads on the hyomandibula; striations on the opercle radiating from the facet for articulation with the hyomandibula; 45 – 47 vertebral centra with 19 – 22 abdominal; anteriormost centra with numerous pits forming an open, lacy bone texture; and short deep lower jaw with the level of articulation anterior to the orbit and with a high coronoid process on the dentary. Differs from members of the suborder Osteoglossoidei (caudal formula I, 7,8, I) by having a caudal formula of I, 8,8, I. Further differs from subgroups within Osteoglossoidei by lacking an elongate pectoral fin ray and reticulate scales (found in many osteoglossids); having abdominal pelvic fins and unexpanded pectoral fin (unlike the anteriorly placed pelvic fins and expanded pectoral fins of Pantodon); having a small anal fin not connected with the caudal fin (unlike the elongate anal fin confluent with the caudal fin found in notopterids); jaws terminal and unmodified (unlike the modifications of the jaws found in mormyrids). Differs from species of † Joffrichthys by having anteriormost abdominal and posterior caudal vertebral centra with many small pits and a network of bone forming a lacy structure, rather than ‘ H-shaped’ (i. e. two large pits laterally separated by a strong bar of bone), and by having a relatively shorter and deeper caudal peduncle. Differs from Hiodontiformes by having a rounded dorsal border to the opercle (without the posterodorsal opercular spine as found in Hiodon and † Eohiodon). Differs from basal osteoglossomorphs by having six rays in the pelvic fin (instead of seven rays in † Wilsonichthys, † Shuleichthys, † Xixiaichthys and hiodontiforms).	en	Murray, Alison M., Zelenitsky, Darla K., Brinkman, Donald B., Neuman, Andrew G.
