Google Maps and Google Earth are very common platforms today to explore maps and satellite images of the earth. But there are many other ways to explore the earth. Some are listed here. 1. Earth Explorer This map is developed by USGS helpful to obtain earth imagery across available geo-spatial data types. Users can navigate via interactive map or text search to obtain Landsat satellite imagery, Radar data, UAS data, digital line graphs, digital elevation model data, aerial photos, Sentinel satellite data, some commercial satellite imagery including IKONOS and OrbView3, land cover data, digital map data from the National Map, and many other datasets. Users can search by exact location via the interactive map or input specific coordinates to view what data types are available. 2. Sentinel Hub This platform developed by Sinergise has Sentinel, Landsat, and other Earth observation imagery easily accessible for browsing, visualization and analysi...

Late Pre Cambrian-Stromatolites from
Dhading Dolomite, Lesser Himalaya
Fossils from Tethys Himalya
•
Stromatolites: found in blue-grey dolomitic rock
sequence of the Kali Gandaki section in Central West Nepal.
Majority of the Nepal stromatolitic
structures can be ascribed to the larger groups of Collonnella and Conophytons.
The algal evolutionary stages in Nepal
have commenced during the Lower Riphean (1260Ma) and continued through the
Middle Riphean period (1260-1000Ma).

: Vidalina martana Far. ; Haurania sp. ; and Nauticulina sp.
Two bivalves : Agropecten sp. and pseudolimae
sp.
Lumachelle: Several species of
ammonites, pelecypods, brachipods, belemnites and foraminifers have been
recognized.
Saligram: ammonites and
forminifers
Kagbeni Formation
Several plant fossils have been recorded
indicating an Wealdian age.
