 These were discovered by Deny King in the workings of his tin mine.The climate was most likely as cool as or cooler than it is at Melaleuca now (an average yearly temperature of 11.5C, an average temperature of the coldest month of 4.5 °C, a mean maximum temperature of the warmest month of 20 °C)
, and possibly wetter, over 2400 mm annually.The leaves and fruiting cones were discovered at different locations, and since the sediment had been removed during mining, the stratigraphy of the fossils is unknown.
