1. Anomalous ammonites: the Cretaceous genus Nipponites.

2. In other areas gas generation occurred during Cretaceous/Tertiary burial.

3. Throughout the last third of the Cretaceous the dinosaurs slowly declined in diversity and numbers.

4. The Cretaceous period in geology did not appear at a given stage in the development of the changes.

5. He says that dinosaur specimens from late Cretaceous rocks reveal low predator/prey ratios of from 3 to 5 percent.

6. The occurrence of fuller's earth in Cretaceous strata from Wiltshire to Yorkshire has been studied.

7. Their fossils are commonest in Triassic, Jurassic and Cretaceous rocks.

8. The last dicynodont: An Australian Cretaceous relict.

9. Because of Yizheng orogeny in Late Cretaceous, braided delta system of Anfeng was formed by rifting in Subei Basin and rising of sedimentary base level.

10. Seeds of Acer are rare compared with the leaves, which can be found in rocks dating back to the Cretaceous period.

11. A distant relation of Halorella, called Peregrinella, is even more remarkable in early Cretaceous rocks.

12. Then followed the long afternoon of the dinosaurs, the 71 million years of the Cretaceous period.

13. Similarly, the huge reptiles which dominated the land, sea, and even the air of the Cretaceous are all gone.

14. Sumatra is composed of old, thick continental crust comprising volcanic rocks of Permian, Cretaceous and Cenozoic age.

15. A whole range of other reptiles were present in the Jurassic and Cretaceous; none of them are dinosaurs.

16. Protagonists of the warm-blooded theory will show some of the horned dinosaurs charging over the Cretaceous plains like furious reptilian rhinoceroses!

17. Faulting is therefore mostly of Jurassic age although during the late Cretaceous it formed the locus for strong inversion and fault-block readjustment.

18. It also caps many of the Jura box-folds, where the Cretaceous succession has been eroded away.

19. Crocodiles and lizards have a fossil record extending back to the Triassic(sentencedict.com), snakes to the Cretaceous.

20. Carboniferous sediments have been affected by low-amplitude Hercynian folding, Mesozoic rift faulting and Cretaceous inversion-related compression and fault re-activation.

21. Species resembling this one in general shape are met with in rocks of Cretaceous and younger age.

22. A few species generally resembling this one occur in Jurassic and Cretaceous rocks.

23. One possible case of paired impacts has been widely discussed in connection with the Cretaceous extinction event.

24. There are a number of species generally similar to this one in rocks of Cretaceous and younger age.

25. Many layers of decaying organic matter built up in Pennsylvania during the Cretaceous, and now it is all coal.

26. It was called the Ruyang Gigantic Sauropod Dinosaurian Fauna by L et al... It represents a new late Early Cretaceous to early Late Cretaceous dinosaurian fauna from China.

27. Field surveys and seismic exploration show that the lowest regional angular unconformity older than the Carboniferous developed between the Cretaceous and the pre-Cretaceous strata.

28. Based on the analysis of core of Subei basin during late Cretaceous and Paleocene Epoch[http://sentencedict.com/cretaceous.html], the authors conclude that Subei Basin was linked with the sea and the deposit was affected by transgression.

29. Because of compaction and cementation by carbonate, silicon and argilla , the pore loss of lower cretaceous reservoir bed of southern part of Shiwu depression is 25%?

30. Deinonychus lived 110 to 100 million years ago. That time was called the Cretaceous period.
