Launching the 2010 expedition, travelling from Antananarivo to Mahajanga via RN2; most of Madagascar's central plateau is completely deforested and covered by exotic grasses and erosion gullies. |
First we prospected at Ampazony, the site that produced the new seacow species Eotheroides lambondrano in 2003. |

After work at Ampazony we crossed the Betsiboka river on the "Bac Baobab" ferry. |
Team members relaxing on the ferry: Tsiory Andrianavalona, Niaina Ramihangihajason, Dan Branch, Lydia Raharivony, and University of Antananarivo Professor and collaborator Rachel Razafimbelo. |
After landing at Katsepy, on the west side of the Betsiboka, we drove west for a full day and arrived at Soalala, a small regional town. These fishing boats at Soalala are hand-made outriggers used for ocean fishing and transport. |
Our second prospection site was Amparafaka, near Soalala, where we found these tall cliffs composed of Pliocene sandstones and Miocene limestones. |
Our third site was Cap Tanjona, a Miocene limestone massif, which projected from the coast into the Mozambique channel. |

Our fourth site: Nosy Mahakamby, a windswept island in the Mozambique channel. |

Our final fieldwork in 2010 was prospection in the Antsirabe region of the central high plateau. This is a typical "Imerina" high plateau landscape with terraced rice fields, grasslands and exotic pine trees grown for timber. |
Searching for fossils in lacustrine sediments. |
Typical village in the Sambaina region, showing two-story houses made from locally-sourced bricks. |
This region has vast expanses of flat land under cultivation (mainly for carrots and cabbage); this was once the northern part of a vast inland lake. |
An active mineral spring found within the carrot fields | Many people are surprised to learn that the ground floor is often reserved for livestock. |
Our very final day of prospection - we had the good fortune to stumble across a local store selling homemade yogurt. |
