История появления акул на планете Наверное, самый древний период когда существовали акулы - это Силурийский период (438 - 408 миллионов лет до нашей эры). Об этом свидетельствуют останки акулоподобных существ в Поволжье, Средней и Центральной Азии, в Прикаспии, даже в Московской области (Фили), на Украине, и на полуострове Мангышлак (Казахстан). Среди зарубежных залежей останков известны многочисленными находками США (штат Огайо), Австралия и многие страны. Далекие предки акул были широко распространены во всех соленых и даже пресных водоемах древности.
