Pego Longo-Carenque tracksite (Cretaceous of Portugal)

Also known as Lisbon

Where: Lisboa, Portugal (38.8° N, 9.3° W: paleocoordinates 28.3° N, 6.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Cane├žas Formation, Cenomanian (100.5 - 93.9 Ma)

• bed-level stratigraphic resolution

Environment/lithology: peritidal; bioturbated, shelly/skeletal, gray, muddy limestone and gray, green claystone

• "deposited during the initiation of a transgressive event"
• "The track bearing layer is a slightly marly, dark grey, bioclastic, bioturbated, reddish-weathering limestone, overlying a grey-green, unfossiliferous clay. The overlying beds are a whitish succession of massive, fossiliferous limestones deposited under normal marine conditions."

Size class: macrofossils

Preservation: mold/impression, trace, concretion

Collected in 1985-1997

Collection methods: surface (in situ),

• saved through conservation efforts resulting in tunneling roadway beneath site; so-called "Battle of Carenque"
