Wildlife of Sierra Leone
Sierra Leone has 15 identified species of primates that include bushbaby, monkeys and a great ape, the common chimpanzee which is Sierra Leone's largest primate. Chimpanzees are found across the country with the 2010 chimpanzee census estimated a wild population in excess of 5500 more than double the number previously thought to live in the country. This is the second largest population of the endangered subspecies of western chimpanzee, after Guinea,
with the largest density in the Loma area, 2.69 individuals per km2, and the Outamba, with 1.21 individuals per km2.
Sauropoda
The best evidence indicates that the most massive were "Argentinosaurus" (120 metric tons), "Puertasaurus" (80 to 100 metric tons ), "Alamosaurus", "Paralititan", "Antarctosaurus" (69 metric tons). There was poor (and now missing) evidence that so-called "Bruhathkayosaurus", might have weighed over 175 metric tons but this has been questioned. The weight of "Amphicoelias fragillimus" was estimated at 122.4 metric tons but 2015 research argued that these estimates may have been highly exaggerated. The largest land animal alive today, the Savannah elephant, weighs no more than .
