Suchomimus tenerensis
读音： SOO-koh-MY-mus ten-er-EN-sis
Tetanurae · Spinosauridae
A long-snouted, fish-eating spinosaurid from the Early Cretaceous of Niger, with a big thumb claw and a low ridge along its back. A close African relative of Baryonyx, it shared its rivers with Nigersaurus and Sarcosuchus.

概览
此内容目前仅提供英文版。
Suchomimus tenerensis lived in what is now the Ténéré Desert of Niger in the Early Cretaceous (Aptian-Albian), among rivers teeming with fish and giant crocodyliforms. Paul Sereno's team found it at Gadoufaoua in 1997, and Sereno and colleagues named it in 1998.
It had a very long, narrow, crocodile-like snout, a large thumb claw and blade-shaped spines over its hips forming a low sail. Its skeleton showed that the enlarged thumb claw and strong arms of spinosaurids evolved before their fish-catching skulls (Sereno et al. 1998).
Its close relationship to Baryonyx from England suggests that spinosaurids crossed the Tethys seaway in the Early Cretaceous; some authors even place it in the genus Baryonyx.
名称含义
"Crocodile mimic", from Greek souchos ("crocodile") and mimos ("mimic"), for its long snout; tenerensis for the Ténéré Desert (Sereno et al. 1998).

系统发育推断 · Spinosaurid phylogeny with Suchomimus
The enlarged thumb claw and robust forelimb evolved in the Jurassic, before the elongate snout; Suchomimus is closest to Baryonyx.
