Geography
Country: Spain


Coordinate: 37° 55' 9" N, 1° 9' 41" W
Coordinate basis: stated in text

Time interval: Early Pliocene

Zone: MN14

Max Ma: 4.997

Min Ma: 4.896

Age basis: paleomag

Geography comments: "8 km SSW of the town of Murcia, and 2.5 km south of El Palmar, on the northern flank of the Carrascoy range mountain"
"correlated with the reverse polarity chron C3n.3r (5.0-4.9 Ma)" and assigned to MN14
this is specifically 4.997 to 4.896 according to Ogg (2020)
based on microfossils, "the underlying erosive surface corresponds to the end-Messinian discontinuity", implying that the reversed section including the fossils is from C3n.3r

Environment
Lithology: sandstone

Taphonomic context: fluvial deposit

Habitat comments: the site's lithology is "a sand and lutite alternating succession" and the sands are mainly "sets of trough and planar cross-stratification... The macrovertebrate fossil remains are mainly located in the conglomeratic layers of the sands or in the basal lag of the sedimentary sets"
the environment is interpreted as "channels through which dunes and megaripples migrate"

Methods
Life forms: carnivores,primates,rodents,ungulates,other small mammals,other reptiles,snakes

Sampling methods: quarry

Sample size: 195 specimens

Years: 2008 - 2011

Sampling comments: "This site was discovered in 2008 as a result of the construction of the MU-31 motorway... Systematic excavations were carried out at the Puerto de la Cadena site in 2009, 2010 and 2011... Large amounts of sediment were also screen-washed using superimposed 4.0, 1.0 and 0.5 mm mesh screens"
the material is in the Museo Arqueológico de Murcia
at least four species of turtles are also present, but specimen counts are unclear
