other remains were assigned in 1907 to the genus Goniopholis as G. hartti. Now residing in the British Museum of Natural History, the fragment of the lower jaw, dorsal scute and two teeth compromising the species G. hartti were reexamined and conclusively placed in the genus Sarcosuchus. Recent findings The next major findings occurred during the expeditions led by the American paleontologist Paul Sereno in 1995 (Aoufous Formation, Morocco), 1997 and the follow-up trip in 2000. Partial skeletons, numerous skulls and 20 tons of assorted other fossils were recovered from the deposits of the Elrhaz Formation, which has been dated as late Aptian or early Albian stages of the Late Cretaceous. It took about a year to prepare the Sarcosuchus remains. Fossils were found in 2010 in the Ifezouane Formation of Morocco. Fossil teeth from the area of Nalut in northwestern Libya, possibly Hauterivian to Barremian in age, might be referable to S. imperator. Indeterminate Sarcosuchus material including dorsal osteoderms in anatomical connection, isolated teeth and fragmentary skeletal remains including a left scapula, mandible fragment, dorsal vertebrae, ilium and a proximal portion of a femur was described from the Oum Ed Dhiab Member in Tunisia in 2018. Paleobiology Growth pattern Sereno took thin sections from trunk osteoderms of an estimated subadult individual (~80% of estimated maximum adult size). Approximately 40 lines of arrested growth (LAG) were counted in these thin sections, suggesting that S. imperator took 50 to 60 years to reach adult size. Given that extant wild crocodylians rarely reach these advanced ages, Sereno suggested that S. imperator achieved its large size by extending its period of rapid, juvenile, growth. A similar growth strategy has been suggested for the equally titanic crocodylian Deinosuchus, based on similar criteria. Diet Based on the broader snout of fully grown S. imperator when compared with the living gharial and other narrow-snouted crocodiles, along with a lack of interlocking of the smooth and sturdy-crowned teeth when the jaws were closed, Sereno et al. hypothesized that S. imperator had a generalized diet similar to that of the Nile crocodile, which would have included large terrestrial prey such as the abundant dinosaurs that lived in the same region. However, a 2014 analysis of a biomechanical model of its skull suggested that unlike Deinosuchus, Sarcosuchus may not have been able to perform the "death roll" maneuver used by extant crocodilians to dismember their prey. This suggests that
