Linhevenator tani
Sandwiched between Linheraptor and Linhenykus in a trifecta of small carnivorous critters from Mongolia's Linhe district described in six months over 2010/2011, Linhevenator emerges as the most anatomically paradoxical of the three. Where Linheraptor embodied the lithe, feathered raptor archetype and Linhenykus startled with its one-fingered hands, Linhevenator presented a troodontid with unexpectedly abbreviated forelimbs—an evolutionary experiment in shrinking grasping appendages within a lineage otherwise celebrated for their bird-like agility and keen senses, sharpened by one of the highest EQs among non-bird dinosaurs. The holotype, catalogued as LH V0021, was recovered from the Wulansuhai Formation near Bayan Mandahu Village. Though its fossils are badly weathered, the specimen remains the most complete troodontid yet known from the Late Cretaceous, offering a rare window into the anatomy of this elusive group.
Troodontids are generally small, bird-like, gracile maniraptorans, often imagined as quick, intelligent omnivores with delicate builds. Linhevenator, however, breaks that mold: it was rather large for a troodontid, stretching close to two meters in length and tipping the scales at 20+ kilos. Its arms, though shortened, were unusually robust, perhaps suited for digging or climbing. Most striking is its raptor-like second toe, armed with a sickle claw larger than those of more basal troodontids, hinting at predatory adaptations beyond the typical grasping and pecking associated with the family. In Linhevenator, size, strength, and unusual weaponry combined in unexpected ways, painting a picture of a predator that was both familiar and strange in the deserts of Cretaceous Inner Mongolia.

(Tan's Linhe Hunter)Etymology
Linhevenator is derived from "Linhe" (the district of Inner Mongolia where the specimen was discovered), and the Latin "venator" (hunter).The species epithet, tani, honours Professor Tan Lin for his contributions to the field of vertebrate paleontology in Inner Mongolia.
Discovery
The remains of Linhevenator were discovered at the "North Canyon" locality in the Wulansuhai Formation, Bayan Mandahu Village, Wulatehouqi,
Linhe District, Inner Mongolia, China, in 2009. The holotype (LH V0021) is a badly weathered partial skeleton.
In the space of six months across 2010–2011, three small theropods from distinct families were described from the Linhe District — Linheraptor exquisitus (Dromaeosauridae), Linhevenator tani (Troodontidae), and Linhenykus monodactylus (Alvarezsauridae) — each showing surprising features in their arms, hunting styles, and in the overall variety of small predators that lived in the Cretaceous ecosystems of Inner Mongolia.
