However, the preserved palaeodiversity and/or tapho-nomic 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 fossil-iferous amber and a dinosaur bonebed have been found in association, and the only one known where 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. 2021 Article https://ddd.uab.cat/record/304758 urn:10.7554/eLife.72477 urn:oai:ddd.uab.cat:304758 urn:oai:egreta.uab.cat:publications/0f52f2a6-071b-499d-9ab0-b67db2550a39 urn:pure_id:171599614 urn:scopus_id:85120179874 urn:pmid:34844669 urn:pmcid:PMC8631943 urn:articleid:2050084Xv10e72477 urn:pmc-uid:8631943 urn:oai:pubmedcentral.nih.gov:8631943 eng Agencia Estatal de Investigación CGL2017-84419 Agencia Estatal de Investigación PGC2018-094034-B-C22 Ministerio de Economía y Competitividad CGL2015-69805-P Agència de Gestió d'Ajuts Universitaris i de Recerca 2017/SGR-824 Agencia Estatal de Investigación BES-2016-076469 Agència de Gestió d'Ajuts Universitaris i de Recerca 2020/FI_B100002 eLife ; Vol. 10 (November 2021), art. e72477 open access Aquest document està subjecte a una llicència d'ús Creative Commons.
