Description: It appears that when you select a date range using the slider on the species page maps, you are shown some occurrences for which no date is given. This becomes evident when, for example, you use this feature to demonstrate the spread of invasive species over time, and the undated occurrences remain visible in decades that actually pre-date their appearance in those locations. In the example given, most of the occurrences shown on the map, with time slider selected for 1960s and before, are gridded data from the European Breeding Bird Atlas with dates n/a. I realise this will all change with the new pages but it would be nice to exclude undated occurrences from these views in a future version of this feature.

Comment: If you select the options on the bottom left where you can change the basis of record, you have the ability to toggle on and off the undated stuff using the "show undated"
