İğneada Floodplain Forests National Park mixed wood. Vine species are the most distinct plants of the forest. Sprecies of European ash ("Fraxinus excelsior"), oak ("Quercus"), alder ("(Alnus"), beech ("Fagaceae") and maple ("Aceraceae") are trees found in the national park forest. Trout ("Oncorhynchus"), smelt ("Osmeridae"), grey mullet ("Mugilidae") are fish species of the national park. Birds like white-tailed eagle ("Haliaeetus albicilla"), European green woodpecker ("Picus viridis"), owl ("Strigiformes"), grey heron ("Ardea cinerea"), European cuckoo ("Cuculus canorus"), kingfisher ("Coraciiformes"), black stork ("Ciconia nigra)") and hoopoe ("Upupa epops") are observed in the area. Among the mammals are wildcat ("Felis silvestris"), wild boar ("Sus scrofa"), hare ("Lepus"), European pine
Origin of birds soft tissue allowed a molecular comparison of cellular anatomy and protein sequencing of collagen tissue published in 2007, both of which indicated that "T. rex" and birds are more closely related to each other than either is to "Alligator". A second molecular study robustly supported the relationship of birds to dinosaurs, though it did not place birds within Theropoda, as expected. This study utilized eight additional collagen sequences extracted from a femur of the "mummified" "Brachylophosaurus canadensis" specimen MOR 2598, a hadrosaur. However, these results have been very controversial. No other peptides of a Mesozoic age have been reported. In
