"There were still conifers and ferns as well, but mostly of the sort that had tiny needle leaves, like junipers, says Bonnie Jacobs. "Sycamores and their relatives would have been among the flowering plants."
The first ornithocheirid remains from North America, discovered in Fort Worth, were described by former SMU student Young-Nam Lee and donated by amateur collector Chris Wadleigh, says SMU's Louis Jacobs.
"The ancient sea that covered Dallas provided the right conditions to preserve marine reptiles and other denizens of the deep, as well as the delicate bones of flying reptiles that fell from their flight to the water below," says Louis Jacobs, a professor in SMU's Huffington Department of Earth Sciences. "The rocks and fossils here record a time not well represented elsewhere in North America. That's why two species of ornithocheirids have been found here but nowhere else, and that's why discoveries of other new fossils are sure to be made by Lance Hall and other fossil lovers."
