“…With a late Albian absolute age obtained for the La Flecha ranch, this fossil represents the oldest record of angiosperm wood for South America, and one of the oldest for the Southern Hemisphere. Previously described Cretaceous angiosperm woods from South America are of Upper Cretaceous age (Milanez 1935;Ragonese 1977;Torres & Rallo 1981;Nishida & Nishida 1987;Mourier et al 1988;Nishida et al 1990;Franco et al 2015;Egerton et al 2016). Thus, this finding increases our knowledge of the diversity of angiosperm organs in the Cretaceous of South America (see Archangelsky et al 2009).…”

“…This conclusion is based on fossil pollen, compressions, and impressions. Fossil angiosperm woods in South America are scarce until the Cenozoic (Archangelsky et al 2009;InsideWood 2004-onwards;Wheeler 2011;Gregory et al 2008); and only a few angiosperm fossil woods have been described from its Late Cretaceous (i.e., Milanez 1935;Torres & Rallo 1981;Nishida & Nishida 1987;Mourier et al 1988;Nishida et al 1990;Franco et al 2015;Egerton et al 2016). In particular, the fossil record of angiosperm woods in central Patagonia is restricted to a few Cenozoic and Late Cretaceous occurrences (i.e., Romero 1970;Petriella 1972;Ragonese 1980;Brea 1998;Brea & Zucol 2006;Raigemborn et al 2009).…”

A new species of Carlquistoxylon from the Early Cretaceous of Patagonia (Chubut province, Argentina): the oldest record of angiosperm wood from South America

et al. 2018

An angiospermous wood from the Lower Cretaceous (upper Albian) of the Cerro Barcino Formation, Chubut Group, central Patagonia, Argentina, is described. Its estimated minimum diameter is 40 cm and it is significant as the oldest known angiosperm wood for South America.It has indistinct growth ring boundaries, vessels solitary and in radial multiples, simple perforation plates, alternate intervessel pits, vessel-ray parenchyma pits oval to horizontally elongated, heterocellular rays, non-septate fibres, axial parenchyma absent, and abundant tyloses. Because this Albian wood has non-septate fibres we assign it to Carlquistoxylon, even though it has a general combination of characters similar to that of Paraphyllanthoxylon, which has septate fibres. The number of vessels per radial multiple, vessel tangential diameter and frequency, vessel-ray parenchyma pitting, and absence of axial parenchyma distinguish the fossil described here from the only previously known species of Carlquistoxylon: Carlquistoxylon nacimientense; therefore, a new species is erected. Because of the close similarities between this new specimen and Paraphyllanthoxylon species, comparisons with all the species included in both genera are provided. Systematic affinities for this wood are discussed considering previous discussions for both Paraphyllanthoxylon and Carlquistoxylon affinities. As the oldest described angiosperm wood in South America to date, this specimen provides critical information on the diversity and growth habit of Cretaceous angiosperms from the Southern Hemisphere.

“…In Colombia, two or three morphotypes of Lauraceae were recognized in the Maastrichtian Guaduas macroflora (Carvalho & al., 2021). In northeastern Argentina, a Cretaceous fossil wood was described as one species in Paraperseoxylon E.A.Wheeler & S.R.Manchester (Franco & al., 2015). Besides the two leaf fossils of Lauraceae from an early Cenozoic deposit in Argentina (Carpenter & al., 2018), Carpenter identified another foliar fossil of crown‐group Lauraceae on a late Paleocene island in the Indian Ocean (Carpenter & al., 2010).…”

The biogeographical history of many lineages within the Lauraceae remains poorly known because of the difficulty of assigning macrofossils to living genera, poor pollen preservation, and the absence of sufficiently resolved or well‐supported phylogenies. Here, we utilize plastid genome sequencing to reinvestigate the phylogenetic and biogeographic history of trees in the tribe Cryptocaryeae, an important component of broad‐leaved forests worldwide, with around 800 species that rely on vertebrate frugivores to disperse their seeds. A new time‐calibrated phylogeny with high support for 176 species was used to infer the biogeographic history and speciation rates based on inferences of BAMM analyses. A monophyletic Cryptocaryeae with Aspidostemon, Beilschmiedia, Cryptocarya, Dahlgrenodendron, and Eusideroxylon clades was confirmed. The five clades of Cryptocaryeae were estimated to share a common ancestor in tropical Africa or Asia in the Early Cretaceous around 123 Ma. The Beilschmiedia and Cryptocarya clades were estimated to have originated in South America around 66 Ma. Extant subclades of the Beilschmiedia clade could colonize Australia by 35 Ma and extant subclades of the Cryptocarya clade could colonize Australia by 42 Ma. Diversification rates of the Beilschmiedia clade accelerated 14 and 12 Ma after its origin and diversification rates of the Cryptocarya clade accelerated 18 Ma after its origin. Over 45% extant Cryptocaryeae species originated in the three periods of accelerated differentiation in the Miocene of Asia and Australia. Long‐distance dispersal has had a major influence on biogeography, with dispersal to Asia likely occurring seven times, Zealandia six times, America three times, Australia three times, Africa twice, and Oceania at least once. Over 70% extant Cryptocaryeae species which diverged before the Quaternary grow in the Southern Hemisphere, while 90% extant Cryptocaryeae species which diverged in the Quaternary grow in the Northern Hemisphere. The Cryptocaryeae originated in and diversified with the first angiosperm‐dominated broad‐leaved evergreen forests, from the Cretaceous to the Paleogene. Long‐distance seed dispersal, probably by birds, although possibly also by flotation, has allowed the tribe to track these forests in space and time, despite a failure to adapt to cold, dry, or highly seasonal environments.

“…Based on the above, we suggest the main tree species in the Upper Cretaceous of SW Uruguay were: Araucariaceae sp., Aspidosperma sp., Prosopis sp., and Jacaranda sp., among others. A study of the wood remnants at the Puerto Yeruá Formation (Argentina), lateral equivalent to the Guichón, Mercedes and Asencio formations, revealed that an extensive woodland composed mainly of Lauraceae trees possibly existed during the late Cretaceous (Franco et al, 2015). It seems thus reasonable to assume that Lauraceae would also have been present in our study area.…”

The Grutas del Palacio is the sector where the Asencio Formation (Upper Cretaceous), which crops out discontinuously in SW Uruguay, is best displayed. The Asencio Formation consists of red terrigenous sediments modified by pedogenesis-lateritic processes. It is constituted from bottom to top by the members Yapeyú (lacustrine) and Palacio (palustrine). The Palacio Member is characterized by the presence of numerous oval-like caves,
