.
Marsh associated the jaw with the avian postcranial elements and published the new data the next year.
An analysis in 1952 concluded the jaw actually belonged to a mosasaur, but a reevaluation in 1967 and new specimens confirmed Marsh's assessment.
This was the first bird described with teeth;
Richard Owen's original description of the London Specimen of ''
Archaeopteryx'' in 1861 did not recognize its associated teeth, and assumed the bird had a beak. This was also the start of Mudge's association with Marsh, as the rivalry between Cope and Marsh (known as the "
Bone Wars") heated up.
Fossils for Marsh
After his dismissal from KSAC in 1874, Mudge wrote to Marsh:
Marsh hired Mudge to lead fossil hunting expeditions. He was assisted on his 1874 expedition by
Samuel Wendell Williston, who started leading his own expeditions in 1877. Mudge primarily focused on the Kansas Chalk from 1874 to 1876, but from 1876 to 1879 he expanded into Colorado discovering some of the first Jurassic dinosaurs in the

.
According to Blackmar, "in one year he shipped over three tons of fossils, etc., to New Haven"

Marsh's rival Cope in turn had Oramel Lucas and
Charles Hazelius Sternberg seeking out new finds. In 1877, Cope's team was making remarkable finds at
Como Bluff, Wyoming near
Cañon City, Colorado, and Marsh sent Mudge to establish a quarry near the location. While the quarry was eventually abandoned because the bones were too fragile to transport, Mudge and Williston discovered the
holotype specimens of ''Allosaurus'' (''A. fragilis'') and ''Diplodocus'' (''D. longus'') in 1877 before the quarry was closed, and both species were named by Marsh, the former in 1877 and the latter in 1878.
Legacy
With John D. Parker of Lincoln College (now
Washburn University), Mudge founded the Kansas Natural History Society in 1867 (which became the Kansas Academy of Science in 1871). He was elected its first president, and published many of his scientific papers in its ''Transactions''.,
[Aber 2007] and he became a fellow of the
American Association for the Advancement of Science in 1878.
He died outside his home of a "stroke of

" on November 21, 1879 and was buried two days later on Cemetery Hill.

Three species were named in his honor. Cope named a mosasaur species ''Liodon mudgei'' in 1871; though it is now considered to be a specimen of ''
Platecarpus tympaniticus'', ''Liodon'' remains as a
junior synonym. The jaw of the ''Ichthyornis'' that Marsh originally believed belonged to a
saurian was named ''Colonosaurus mudgei''.
Lesquerenx also a named a species of
oak ''Quercus mudgeii'' in 1872. Mudge himself named the Fort Hays member of the
Niobrara Formation in 1876.
During his career, he discovered specimens of

Beliefs and personality
Mudge was a member of temperance organizations, and during his tenure as mayor of Lynn closed many saloons.
In Kentucky and later in abolitionist Kansas, was known for opposition to slavery. Parker notes that during the Civil War:
He had a keen interest in natural history. His protégé Williston wrote in 1898:
Mudge had a systematic approach, and kept excellent records of both the locality of his discoveries and the actual specimens. From Dale Russell's 1967 ''Systematics and Morphology of American Mosasaurs'':
Publications
Mudge was not a prolific publisher of scientific papers. According to the Kansas Geological Survey Online Bibliography of Geology,
[KGS Online Bibliography of Geology.] his entire output was contained in twenty-two publications, and most were very short.
