Anatomically, the Pleistocene specimens are consistent with modern populations, which currently range from Maryland to Alabama, reflecting a long-term evolutionary success in the southeastern United States. The species' reliance on permanent water bodies, such as marshes and swamps, has likely served as a buffer against the climatic fluctuations that characterized the Pleistocene, allowing the siren to maintain its specialized, paedomorphic body plan over geological time scales.\u003c\/p\u003e\n\u003chr id=\"horizontalrule\"\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"MinuteMan26","offers":[{"title":"Default Title","offer_id":51980949356824,"sku":"06ALL378","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1250\/0441\/files\/5U8A6605_edf64dcc-d2db-4498-935e-c9986f09d785.jpg?v=1776832143","url":"https:\/\/www.fossilageminerals.com\/products\/7-7-indeterminate-snake-vertebrae-fossil-bones-pleistocene-age-florida-06all378","provider":"Fossil Age Minerals","version":"1.0","type":"link"}
