| Abstract | (unpublished)
Conularina triangulata (Raymond, 1905), the genotype of Conularina Sinclair, 1942, is a rare, early Late Ordovician conulariid (Cnidaria, Scyphozoa; Van Iten et al., 2006) having
three sides or faces instead of four (Sinclair, 1942, fig. 9; Van Iten, 1992, text-fig. 3E). Originally described from the Valcour Formation (early Sandbian; Dix et al., 2013) on Valcour Island, New York (Sinclair, 1942), C. triangulata has since
been found in laterally equivalent strata of the upper Laval Formation (-Upper Chazy-; Sinclair, 1942) in Laval, Québec, Canada (Sinclair, 1942). From this same unit and area, Sinclair (1942) erected three new, four-sided species of Conularina (C.
irrasa, C. raymondi, and C. undosa), and he erected a single four-sided species (C. narrawayi) from the Ottawa Formation (now the Sandbian-Katian Ottawa Group; Dix et al., 2013) at Tétreauville (now Gatineau), Québec. Subsequently, Jerre (1994)
reported the occurrence of two species of Conularina in the Upper Ordovician of Sweden. Jerre (1994) also proposed that Eoconularia- forensis Sinclair, 1946 from the Upper Ordovician Citadelle Formation (-Quebec City- Formation; Sinclair, 1946) in
Québec City, Québec (Promontoire de Québec thrust sheet, Appalachian Humber Zone, Allochtonous Domain; Castonguay et al., 2002) is a species of Conularina. |
| Summary | (Plain Language Summary, not published)
The publication discusses a rare sea creature called Conularina triangulata, which lived in the Late Ordovician period, over 450 million years ago. This
creature is a type of conulariid, belonging to the group of animals known as Cnidaria, which includes jellyfish and corals.
The researchers studied the fossils of Conularina triangulata found in different locations, like New York and Quebec,
Canada. They discovered that this species had a unique triangular shape, unlike the typical four-sided conulariids. The study also mentions other related species with different numbers of sides.
This research helps scientists understand the
diversity of life in ancient oceans and how these creatures evolved. It tells us about the different shapes and forms they took in response to their environment.
While this study might not have immediate practical applications, it adds to our
knowledge of Earth's history and the various life forms that existed in the past. It's like solving a puzzle that helps us better understand the story of life on our planet. |
