Mazzaella (conodont)
''Mazzaella'' is an extinct genus of Late Triassic ozarkodinid conodonts in the family Gondolellidae. They are found in mid- Julian sediments of the Tethys Ocean, including strata in Europe (Germany, Hungary, Italy) and Turkey. The type species of ''Mazzaella'', ''Mazzaella carnica'', was originally designated as ''Epigondolella carnica'' Krystyn (1975). It has been used as an index fossil, defining the middle of three Julian conodont biozones according to a 2018 update to Tethyan conodont biostratigraphy. The genus also includes a rarer species, ''Mazzaella baloghi'', originally ''Metapolygnathus baloghi'' Kovacs (1977). ''Mazzaella'' appears to be a descendant of ''Metapolygnathus ( Quadralella)'' ''auriformis''. Relative to ''Metapolygnathus'', ''Mazzaella'' has a moderately elongated free blade and strong platform nodes. The platform is broader and the free blade is proportionally longer in ''M. baloghi'', relative to ''M. carnica''. Although its overall shape is similar to ...

Conodont
Conodonts (Greek ''kōnos'', "cone", + ''odont'', "tooth") are an extinct group of agnathan (jawless) vertebrates resembling eels, classified in the class Conodonta. For many years, they were known only from their tooth-like oral elements, which are usually found in isolation and are now called conodont elements. Knowledge about soft tissues remains limited. They existed in the world's oceans for over 300 million years, from the Cambrian to the beginning of the Jurassic. Conodont elements are widely used as index fossils, fossils used to define and identify geological periods. The animals are also called Conodontophora (conodont bearers) to avoid ambiguity. Discovery and understanding of conodonts The teeth-like fossils of the conodont were first discovered by Heinz Christian Pander and the results published in Saint Petersburg, Russia, in 1856. The name ''pander'' is commonly used in scientific names of conodonts. It was only in the early 1980s that the first fossil evidence of ...

Maurits Lindström
Maurits Lindström (10 May 1932 – 14 November 2009) was a Swedish geologist and paleontologist. Lindströms initial work was divided among two topics conodont paleontology and the structural geology of the Scandinavian Caledonides in Lappland. In 1970, he described the conodont families Cordylodontidae, Gondolellidae, Proconodontidae and Rhipidognathidae. In 1971, he described the conodont genera '' Baltoniodus'', '' Microzarkodina'' and ''Paracordylodus''.Vom Anfang, Hochstand und Ende eines Epikontinentalmeeres. Maurits Lindström, Geologische Rundschau, March 1971, Volume 60, Issue 2, pages 419-438, Lindström published conodont studies up to 1987 after which he only supervised students working with conodonts. In the late 1980s Lindström begun to study ancient impact craters in the Fennoscandian Shield. His studies have confirmed earlier speculations that Tvären and Lockne are craters.
