The discovery, detailed in&nbsp;<a href=\"http:\/\/dx.doi.org\/10.1098\/rspb.2024.2891\"><em>Proceedings of the Royal Society B<\/em><\/a>, reveals that sebecids, swift, carnivorous reptiles resembling &#8220;crocodile greyhounds&#8221;, thrived on Caribbean islands millions of years after their mainland relatives went extinct.<\/p>\n\n\n\n<p>The fossils, including a serrated tooth and vertebrae found in the Dominican Republic, belong to&nbsp;<em>Sebecus<\/em>, a sebecid species that once dominated South America as apex predators after the dinosaurs\u2019 demise. Standing up to 20 feet long with armored skin and agile limbs, these creatures hunted prey on land, unlike modern crocodiles. The Caribbean findings, dating back 18\u201329 million years, suggest sebecids survived there 5 million years longer than elsewhere, possibly due to temporary land bridges from South America, as proposed by the GAARlandia hypothesis.<\/p>\n\n\n\n<p>\u201cThis emotion of finding the fossil and realizing what it is\u2014it\u2019s indescribable,\u201d said lead author L\u00e1zaro Vi\u00f1ola Lopez, a University of Florida graduate researcher.<\/p>\n\n\n\n<p>The discovery aligns with the idea of islands as \u201cmuseums of biodiversity,\u201d preserving species long after their mainland extinction. Yet, uncovering such fossils is rare due to the Caribbean\u2019s erosive climate. Roadwork in the Dominican Republic accidentally exposed the site, enabling the breakthrough.<\/p>\n\n\n\n<p>The study reshapes understanding of the Caribbean\u2019s prehistoric food chain, hinting at more undiscovered giants. As co-author Jonathan Bloch noted, \u201cThe presence of a large predator is different from what we imagined.\u201d With ongoing explorations, this sebecid may herald a wave of fossil revelations\u2014what Vi\u00f1ola-Lopez calls \u201cthe tip of the iceberg.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Paleontologists have uncovered fossils of a massive, land-dwelling crocodile-like predator in the Caribbean, challenging long-held assumptions about the region\u2019s ancient ecosystems.
