Until recently Mesozoic Radiolaria were ignored in biostratigraphic investigations. This
group of planktonic microfossils was neglected because most workers considered them to be too small and difficult to
work with and to be universally long ranging.
Investigations now in progress indicate that Radiolaria evolved very rapidly during Mesozoic times. In fact,
many genera and species are short ranging, cosmopolitan, and quite distinctive. Because it is now possible to
separate matrix-free specimens from radiolarian cherts. Radiolaria are rapidly becoming the most important group
of fossils in interpreting the stratigraphy and in turn the structure of many complex orogenic belts (e.g., Semail Ophiolite
and Hawasina Complex of Oman) throughout the world.
In the present report eleven new species and three new genera are described from the Lover Jurassic of Turkey
and two new species are described from the Jurassic of North America.

LOWER JURASSIC RADIOLARIA, THE GÜMÜŞLÜ, ALLOCHTON OF SOUTHWESTERN TURKEY

TÜRKİYE'NİN GÜNEYBATISINDAKİ (ORTA TOROSLAR) ALLOKTON GÜMÜŞLÜ BİRİMİNDE BULUNAN ALT JURA RADYOLERLERİ

 Mesozoyik radyolerleri, yakın zamanlara kadar, biyostratigrafik etütlerde dikkate alınmamaktaydı.
Söz konusu grubu oluşturan planktonik mikrofosillerin çok küçük ve evrensel olarak uzun bir zaman aralığında yaşamış
olmaları, araştırmacılar tarafından biyostratigrafik etütlerde dikkate alınmamalarına yol açmıştır.
Halen devam etmekte olan çalışmalar, radyolerlerin, Mesozoyikte hızlı bir evrim gösterdiklerine işaret etmektedir.
Gerçekten de bazı cinsler ve türler kısa zaman aralığında yaşamış, özel ortam ve koşul aramamıştır. Günümüzde radyolarit
çörtlerde bulunan numunelerin matriksten ayrılmasının mümkün olabilmesi nedeniyle radyolerler, stratigrafinin ve kompleks
orojenik kuşaklardaki yapının yorumlanmasında çok önemli bir yer tutmaktadırlar (örneğin Oman'daki Şemail
ofiyolitleri ve Hawasina kompleksi gibi).
Bu yayında, Türkiye'deki Alt Jurada bulunan yeni onbir tür ve üç cinsle birlikte Kuzey Amerikandaki Jurada bulunan
iki yeni türün tanımı yapılmaktadır.
