In January 2019 Leonid Glikman would have been 90 years old,
if he hadn’t died 19 years ago. One of the brightest Soviet researchers of
fossil sharks dedicated his life to studying the Cretaceous and Cenozoic sharks
and rays of the USSR, paying particular attention to the lamnoid sharks. The
most productive period of his work between 1950 and 1970 he spent in former
Leningrad, now St. Petersburg. It is then that he carried out intensive field
studies, gathered a collection of teeth of fossil sharks, wrote 60% of his scientific
works!
An outstanding Soviet researcher of fossil sharks Leonid
Glikman produced works which brought the national paleoichthyology to a new
level. His contribution to the world science is widely recognized and highly
appreciated by foreign experts. Glikman’s detailed study of complex issues of
shark taxonomy and the ways of their evolution, versatile processing of the
collection materials and ingenious interpretation of the obtained data changed
the scientist’s view on the sharks system, redefining their significance for
biostratigraphy.
Glikman’s collection of the remains of fossil elasmobranchii was given to the State
Darwin Museum in 1982. Comprising around
120,000 specimens the collection has retained its great scientific value. This
is the largest in the country (and one of the largest in the world) collection
of fossil elasmobranchii teeth, covering the period of 150 million years (from
the late Jurassic to the present). Glikman mostly himself gathered the exhibits
between late 1940s and 1980s in various parts of the Volga region, Ukraine,
Kazakhstan and Central Asia. Some of the items were passed to Leonid by other
geologists and paleontologists, such as V. I. Zhelezko, V. V. Menner, D. V.
Obruchev. Unique samples of fossil shark teeth were collected by the research
vessels “Vityaz”, “Ob” and “Lomonosov” at the bottom of the Pacific and Indian
Oceans.
Leonid Glikman wrote two large monographs based on the
collection materials – “Sharks of the Paleogene and their stratigraphic significance”
(1964) and “Evolution of cretaceous and cenozoic lamnoid sharks” (1980), as
well as more than 30 articles describing new species and genera. The collection
contains a number of type specimens (holotypes and lectotypes), which
significantly increases its scientific value.
