Abstract

Dinosaur bonebeds with amber content, yet scarce, offer a superior wealth and quality
of data on ancient terrestrial ecosystems. However, the preserved palaeodiversity and/or taphonomic characteristics of these exceptional localities had hitherto limited their palaeobiological
potential. Here, we describe the amber from the Lower Cretaceous dinosaur bonebed of Ariño
(Teruel, Spain) using a multidisciplinary approach. Amber is found in both a root layer with amber
strictly in situ and a litter layer mainly composed of aerial pieces unusually rich in bioinclusions,
encompassing 11 insect orders, arachnids, and a few plant and vertebrate remains, including a
feather. Additional palaeontological data—charophytes, palynomorphs, ostracods— are provided.
Ariño arguably represents the most prolific and palaeobiologically diverse locality in which fossiliferous amber and a dinosaur bonebed have been found in association, and the only one knownwhere the vast majority of the palaeontological assemblage suffered no or low-grade pre-burial
transport. This has unlocked unprecedentedly complete and reliable palaeoecological data out of
two complementary windows of preservation—the bonebed and the amber—from the same site.
