Borogovia is a troodontid theropod dinosaur genus which lived during the Late Cretaceous Period, in what is now Mongolia. Borogovia_sentence_0

In 1971, a Polish-Mongolian expedition discovered the remains of a small theropod at the Altan Ula IV site, in the Nemegt Basin of Ömnögovĭ province. Borogovia_sentence_1

In 1982, the find was reported by Halszka Osmólska and considered by her to be a possible specimen of Saurornithoides. Borogovia_sentence_2

Later she concluded that it represented a species new to science. Borogovia_sentence_3

In 1987, Osmólska named and described the type species Borogovia gracilicrus. Borogovia_sentence_4

The generic name is derived from the fantasy creatures known as 'borogoves' in the Lewis Carroll poem "Jabberwocky", in his Alice's Adventures in Wonderland. Borogovia_sentence_5

The specific name is a combination of Latin gracilis, "lightly built", and crus, "shin", in reference to the elegant build of the lower leg. Borogovia_sentence_6

The holotype specimen, ZPAL MgD-I/174, was found in the Nemegt Formation, dating from the early Maastrichtian. Borogovia_sentence_7

It consists of two lower legs of a single individual, including fragments of both tibiotarsi, the undersides of both metatarsi and the second, third and fourth toes of each foot. Borogovia_sentence_8

The tibiotarsi have an estimated length of twenty-eight centimetres. Borogovia_sentence_9

Borogovia is about two meters (6 feet) long, weighing some twenty kilograms (forty-five pounds). Borogovia_sentence_10

The tibiotarsus is very elongated. Borogovia_sentence_11

The third toe is narrow. Borogovia_sentence_12

The second phalanx of the second toe is short. Borogovia_sentence_13

The claw of the second toe is short and relatively flat. Borogovia_sentence_14

Osmólska claimed that the second toe could not be hyperextended, and suggested that it had regained a weight-bearing function, compensating for the weakness of the third toe. Borogovia_sentence_15

Borogovia was assigned by Osmólska to the Troodontidae in 1987. Borogovia_sentence_16
