They reported that Asian hadrosaurs appear to have migrated over from North America during the Late Cretaceous
. However, Gobihadros and its close Asian relatives seem to disappear as these new hadrosaurs enter Asia, suggesting that the invaders might have ultimately outcompeted species like Gobihadros.
"The results of our study suggest that dinosaurs as a whole were adaptable animals, capable of coping with the environmental changes and climatic fluctuations that happened during the last few million years of the Late Cretaceous
. Climate change over prolonged time scales did not cause a long-term decline of dinosaurs through the last stages of this period."
of Pakistan preserves thick marine succession in the Upper Indus Basin and the Sulaiman and Kirthar belts (Jones, 1961; Shah, 2009).
Conversely, the strata continuity of the East fault depression is weak, the later transformation is strong, the Cretaceous
strata are not developed, and the seismic data quality is poor (Fig.
The deltaic sedimentary unit of Tertiary age in the Rio del Rey Basin is an eastward extension of the Niger Delta, while the Cretaceous
is the continuation of the Calabar Flank.
Five of the cores contain layers about 86 million to 100 million years old, in the Late Cretaceous
. According to seismic data, these were interrupted by subtle angular unconformities, the Paleogene mid-Brookian unconformity in one and the Pliocene-Pleistocene in four.
In particular, the dinosaur's long cochlea, a part of the inner ear, is a signature of bigger, badder late Cretaceous
furball displays the entire structural diversity of modern mammalian skin and hairs."
The presence of kaolinite in Lower Cretaceous
materials of Alava Block, Spain is also attributed to inheritance from soils developed on rocks in the source area (Sanguesa et al., 2000).
(2015) report on new remains belonging to the holotype specimen of Delapparentia turolensis, a large-sized iguanodont from the Early Cretaceous
of Galve in Teruel (originally described by Ruiz-Omenaca, 2011).
Bachmann, in Argentina have identified the new diplodocid sauropod from the early Cretaceous
period in Patagonia, Argentina.
Dating from the Cretaceous
period, the seven eggs are somewhere between 65 and 145 million years old and were discovered in the Gobi desert in China.
