The formation dates from the Kimmeridgian-Tithonian, and the fossil is about 149.2 million years old. In March 2019, the Museu da Lourinhã carried out further excavations uncovering additional elements of the same specimen. Vieira donated the original find to the museum. The specimen was prepared by Carla Alexandra Tomás, Micael Martinho, Laura de Jorge and Carla Hernandez. It consists of an incomplete premaxillary rostrum, a fragment of the maxillae, two isolated partial teeth, and three or four fragmentary cervical vertebrae.
