Late Jurassic
Tiaojishan Fm (Callovian-Oxfordian)
Hebei, China

Length: 25 cm


Yi qi is probably the biggest paleontological sensation of the first part of year 2015. Known from a well preserved partial articulated skeleton, each arm of this little theropod has a long rod-like supplementary bone called styliform element. This together with patches of preserved membranous tissue yield the intriguing possibility that Yi qi sported bat-like wings. The name Yi qi meaning "strange wing" in mandarin is the shortest one ever given to a dinosaur (Incidentally, it equals in length the scientific name of a Chinese bat, Ia io).

Pituriaspis is the best known of the two representatives of a small group of armored jawless fish called Pituriaspids. The generic name derived from the aboriginal word for a hallucinogenic drug called pituri because the author who described it though he was hallucinating when he discovered the bizarre fossil.

Lampreys probably appear very early during the Paleozoic period but their rudimentary skeletons made of cartilage mean that they are only very rarely preserved in the fossil record. Priscomyzon from the Late Devonian of South Africa is to date the earliest known lamprey.

The name of this Early carboniferous tetrapod means "creature of the black lagoon" in reference to the locality of East Kirkton (and not of the 1954 movie of the same name as indicated in a certain popular encyclopedia). It has a mixture of amphibian and reptilian characteristics and its exact affinities are unknown.

This medium size and uncommon ichthyosaur from the Late Jurassic is known from fragmentary remains. It was characterized by relatively small front paddles, thus its generic name (which means "wide wing/paddle"). The larger species Brachypterygius mordax (up to 5 meters) may or may not be the same as the type species B. extremus.
