ALT Top: plot showing the change in body mass in paroxyclaenids through time. Time scale on the left shows the Palaeogene (56 to 22 million years ago from bottom to top). The main, blue shaded, area shows the time range for a number of mammal taxa with their estimated body mass on the horizontal axis; from 0.5 kg on the left to the largest Welcommoides gurki from Pakistan at about 4.25kg on the right. On the far right is an oxygen isotope curve. Underneath is a map of world palaeogeography showing a possible dispersal route from Europe to Pakistan. At the bottom left are two black and white images for teeth: an upper and lower molar of Welcommoides gurki; UM/DBC 2229 (upper molar) and UM/DBC 2225 (lower molar) both in labial view, each with a 2 mm scale bar.
