Data from: Genetic consequences of population expansions and contractions in the common hippopotamus (Hippopotamus amphibius) since the Late Pleistocene
Over the past two decades, an increasing amount of phylogeographic work has substantially improved our understanding of African biogeography, in particular the role played by Pleistocene pluvial–drought cycles on terrestrial vertebrates. However, still little is known on the evolutionary history of semi-aquatic animals, which faced tremendous challenges imposed by unpredictable availability of water resources. In this study, we investigate the Late Pleistocene history of the common hippopotamus (Hippopotamus amphibius), using mitochondrial and nuclear DNA sequence variation and range-wide sampling. We documented a global demographic and spatial expansion approximately 0.1–0.3 Myr ago, most likely associated with an episode of massive drainage overflow. These events presumably enabled a historical continent-wide gene flow among hippopotamus populations, and hence, no clear continental-scale genetic structuring remains. Nevertheless, present-day hippopotamus populations are genetically disconnected, probably as a result of the mid-Holocene aridification and contemporary anthropogenic pressures. This unique pattern contrasts with the biogeographic paradigms established for savannah-adapted ungulate mammals and should be further investigated in other water-associated taxa. Our study has important consequences for the conservation of the hippo, an emblematic but threatened species that requires specific protection to curtail its long-term decline.
Hippopotamus Right Radius and Ulna
This is the right forearm, comprised of the fused radius and ulna of a juvenile hippopotamus (*Hippopotamus amphibius*) skeleton given to the Lapworth Museum by Russell Coope. It is very robust, and large muscle attachment points such as on the olecranon process that extends behind the elbow joint allow the hippo to support its heavy body and move with surprising speed. This specimen was digitised by Jack Mayer Wood using photogrammetry, and is part of a collection of bones from this individual hippo that have been digitised. Source: Objaverse 1.0 / Sketchfab
Hippopotamus Right Tibia and Fibula
This is the right lower leg, comprised of the tibia and fibula, of a juvenile hippopotamus (*Hippopotamus amphibius*) skeleton given to the Lapworth Museum by Russell Coope. It is robust and has large muscle attachment points to support the substantial weight of the hippo. This specimen was digitised by Jack Mayer Wood using photogrammetry, and is part of a collection of bones from this individual hippo that have been digitised. Source: Objaverse 1.0 / Sketchfab
Hippopotamus Right Humerus
This is the right humerus of a juvenile hippopotamus (*Hippopotamus amphibius*) skeleton given to the Lapworth Museum by Russell Coope. It is notably robust, and several large muscle attachment sites provide anchors to powerful muscles that support the weight of the hippo and allow it to move at high speeds when it feels like it. This specimen was digitised by Jack Mayer Wood using photogrammetry, and is part of a collection of bones from this individual hippo that have been digitised. Source: Objaverse 1.0 / Sketchfab

Hippopotamus Sacrum
These fused vertebrae form the sacrum, the portion of the spine that connects to the pelvis, of a juvenile hippopotamus (*Hippopotamus amphibius*) skeleton given to the Lapworth Museum by Russell Coope. Significant remains of dried connective tissue have created some strange artefacts on this digital model, but the anatomy is largely unobscured. This specimen was digitised by Jack Mayer Wood using photogrammetry, and is part of a collection of bones from this individual hippo that have been digitised. Source: Objaverse 1.0 / Sketchfab

Common hippo hind limb in medial view with the fascia lata removed: dark grey indicates muscles dissected in specimen no. 25308, and light grey indicates muscle origins described by Gratiolet (1867) and Windle & Parsons (1903). As a result of necropsy damage, origins were not preserved in specimen no. 25308, but this information was available in the existing literature. Asterisk (*) indicates the location of the patella deep to the fibres of the tensor fasciae latae.
Figure 2 in Mitochondrial sequences of the extinct Cypriot pygmy hippopotamus confirm its phylogenetic placement
Figure 2. Phylogenetic relationships among the extinct Hippopotamus minor and the two extant hippopotami based on the completeMT dataset and the Bayesian inference BEAST method. Neoceti was used as an outgroup to root the tree. The red asterisk indicates the calibration point of the BEAST analysis. Numbers next to the nodes correspond to the estimated divergence times. Numbers on the branches (within brackets) are bootstrap values for the maximum likelihood and neighbor-joining methods and posterior probabilities for the Bayesian inference (BI and BEAST) methods. The embedded photograph shows one of the Cypriot pygmy hippopotamus petrous bones that was sampled to generate the mitogenomic data used in the phylogenetic analyses. Photo credit: Nikolaos Psonis.

Hippopotamus Right Scapula
This is the right scapula (shoulder blade) of a juvenile hippopotamus (*Hippopotamus amphibius*) skeleton given to the Lapworth Museum by Russell Coope. Its broad surface and large spine and acromion would anchor powerful shoulder and neck muscles in life. This specimen was digitised by Jack Mayer Wood using photogrammetry, and is part of a collection of bones from this individual hippo that have been digitised. Source: Objaverse 1.0 / Sketchfab
