Tamarro insperatus

(Unexpected Fantastic Creature)Etymology
Tamarro is a Catalan word referring to a small and elusive fantastic creature from the regional Pallars county folklore. The species epithet, insperatus, means "unexpected" in Latin, in reference to the unexpected discovery of the specimen.
ZooBank registry: urn:lsid:zoobank.org:act:88919F32-2AE8-4587-AB8F-5D5852FA7FF5.
Discovery
The remains of Tamarro were discovered in in the Talarn Formation (Tremp Group) at the Sant Romà d’Abella site, Pallars Jussà county, Lleida province, Catalonia, Spain, by a team of palaeontologists from the Museu de la Conca Dellà (MCD) in September 2003.
The holotype (MCD-7073) is a partial foot bone (right metatarsal II).
The Talarn formation has also yielded a styracosternan ornithopod called Calvarius which, funnily enough, is also known from just a single metatarsal (IV).
