    Good question.


    Much of the answer is speculation, because in the Wigan area any rocks that were deposited during the Cretaceous no longer exist. Therefore we don't have fossils from that time and place, and we don't even have the rocks (from which we might have been able to make a better interpretation of the environment). It is thought that the Cretaceous fluvial deposits and chalk (now prominent in the SE of England) extended over much of Britain, and until the late Cretaceous extinction event, reptiles could have been present (

    That actually states: "Reptiles were the main large predators and herbivores of the Cretaceous world and dominated both terrestrial and marine habitats. Many species of dinosaurs occurred and their remains are commonly found in the Lower Cretaceous river deposits of the Weald Group."

    So Iguanodon could have been in the area in the early Cretaceous.

    The habitat: that's answered as best I can in the same reference.


    Wish I could give you more detail and more confidence.

      I would expect tundra, with the edge of the ice-sheet in Scotland and glaciers in the Lake District.

      Trees (boreal forest) would not have emerged. There would be low growing vegetation, such as the Dryas octopetala after which the Dryas was named, dwarf willows, lichen, etc.


      However, it may have been relatively dry, going on this paper:

      Walker, M. J. C. (2004). "A Lateglacial pollen record from Hallsenna Moor, near Seascale, Cumbria, NW England, with evidence for arid conditions during the Loch Lomond (Younger Dryas) Stadial and early Holocene". Proceedings of the Yorkshire Geological Society 55: 33–42.


      So that tundra-style vegetation may have been thin on the ground; pioneer.

        Dear tjharte -  response to original post only


        Sorry, this is not possible to answer because we do not have evidence. At any location, the rocks exposed provide the evidence through the types of fossil specimens and rocks (sand, clay, limestone etc.) we can think of them as providing .... 'windows back through time', providing a glimpse of the world at that point in time in that specific locality - but not everything. If the rocks of that age are not available, we cannot know.


        No rocks /fossils = no data = no interpretation ....

        Kind regards,
