Sarcosuchus: geant crocodolid from the Early Cretaceous reaching 9 m long and weighing 3-3,9 tons...

" The skull of Deinosuchus, the extinct genus of crocodilian related to the modern alligator. "
After Deinosuchus (at the previous #80), Sarcosuchus... This comparative picture is so eloquent !
" Sarcosuchus and human skull comparison. The largest known skull of Sarcosuchus is 5.2 feet long and was used to estimate the size of this crocodyliformes. Using skull as a based of measurement of the length is a common method to estimate the size of crocodiles and crocodile-like reptiles. ".
" Sarcosuchus is a genus of crocodyliform and distant relative of living crocodylians that lived ~129-112 million years ago. It dates from the Early Cretaceous Period of what is now Africa and South America. It was one of the largest crocodile-line reptiles, reaching an average estimate of 9 meters and 3.5 tons but estimated to grow up to 9.5 m in body length and weigh up to 4.7 tons.
Mass: 8,000 kg Lived: 145 million years ago - 93.5 million years ago (Aptian - Cenomanian) Scientific name: Sarcosuchus (Flesh crocodile) Phylum: Chordata Rank: Genus Higher classification: Pholidosauridae. "

Purussaurus brasilicus
This genus has been known for more than 100 years but recently specimens, especially Campbell and Frailey's reconstruction of a well preserved skull, showed these alligatoroids to be broad headed high skulled monsters with 2 meter skulls, estimated of st least 12 meters long and estimated weight of at least 10 tons. A jaw fragment from the same genus has been found that extrapolates to an even larger individual than the 2 m skull, with a TBL estimated at slightly over 13,5 m.

Only known from fragmental bones, partial skull and lower jaw...
